Overview
Manufactured in the UK, S611 is Eaton's revolutionized reduced voltage softstarter with its advanced feature set and user-friendly interface module to enhance system performance and reduce commissioning time. The S611 is favorable for heavy-duty applications due to its conformally coated PCBs and its kick-start function that enables soft starting of high inertia loads. The protection capabilities of the S611 are more powerful leading to a longer mechanical life along with consistent protection against heavy-duty applications.
The S611 soft starter design makes it capable of controlling the acceleration and deceleration of three-phase motors, the S611 soft starter uses Silicon Controlled Rectifiers (SCRs) to control the voltage to soft start and soft stop the motor. After the motor is started, internal run bypass contactors close, resulting in the motor running directly across-the-line. The built-in solid-state overload protects the motor from overload conditions with sophisticated algorithms that model true motor heating, resulting in better motor protection and fewer nuisance trips. The S611 supports 3-phase motors up to 600 V as well as 26 - 414 amps.
Besides the robust performance, the S611 is available in NEMA 1, 12, 3R, 4, and 4X enclosures. The number of options available for the differing enclosures creates versatility along with the robustness of the drive makes it favorable for extending the life of a system in a wide variety of environment conditions.
Installation of the S611 is made simple with the keyhole mounts. Integrated overload protection and internal-run bypass contactors-which eliminate the need and complexity of additional devices-reduces panel size, installation time, and assembly. Parameter configuration is done via the user interface. The new user interface also streamlines installation, setup, maintenance and monitoring.
The flexibility of the S611 is also empowered by the optional accessories, including user interface remote mounting kit, DeviceNet, Modbus TCP, EtherNet/IP, and PROFIBUS.
Key features of the S611:
- Integrated run bypass and overload
- Severe duty capable
- Sophisticated pump algorithm

- Protective Features
- Motor Overload
- The overload meets applicable requirements for a motor overload protective device. The overload protects the motor from over heat conditions with the use of sophisticated algorithms that model true motor heating, resulting in superior motor protection and fewer nuisance trips.
- Short Circuit
- Short circuit coordination ratings with both fuses and Eaton molded case circuit breakers are available providing customers with design flexibility. The S611 has short circuit coordination ratings as an open component, an enclosed starter, and in a motor control center. The short circuit ratings can go up to 100 kA depending on application configuration.
- Jam
- Jam protection prevents the stress and damage from a jam during normal run. After the motor is started, a current greater than 300% FLA setting will cause the starter to trip on a jam fault.
- Stall
- Stall protection prevents stress and damage to a motor that has not come up to speed, or stalled after the soft start time. The S611 will trip to protect the system in the event that the motor did not get to the rated speed in the defined soft start period. A current greater than 200% FLA at the end of the soft start period will cause the starter to trip on a stall fault.
- Pole Over Temperature
- The S611 is equipped with sensors that monitor the temperature of the power poles. Over temperature protection occurs if the device's thermal capacity is exceeded. The soft starter will trip in over temperature conditions, preventing device failure.
- Phase Loss
- The S611 will detect a phase loss and trip if any phase current drops below a present value. The phase loss trip level is adjustable from 0% to 100% of the average of the other two phase levels with an adjustable trip delay of 0.1 to 60 seconds.
- Phase Imbalance
- The S611 will detect both current and voltage phase imbalances and trip if any phase becomes imbalanced as compared to the average of the other two phases. The phase current imbalance trip level is adjustable from 0% to 100% of the average of the current in the other two phases with an adjustable trip delay of 0.1 to 60 seconds.
- Reset Mode
- The S611 can be set up for automatic or manual reset on trip. The manual reset mode requires the operator to physically press the RESET button located on the soft starter. The overload can be manually reset through the UI or through the communications network.
- The automatic reset mod allows the soft starter to be automatically reset as soon as the trip condition is no longer present. With the automatic reset mod, after the fault is no longer present, the motor will be restarted as soon as the valid start signal is present.
- Phase Reversal
- The S611 will determine if the proper line phase sequence is present by default. The device will trip if the line phase sequence is something other A-B-C. The S611 can be configured to operate under reversed phase conditions (A-C-B).
- Shorted SCR Detection
- The S611 monitors the operation of the power poles and will trip under a shorted SCR condition.
- Open SCR Detection
- The S611 monitors the operation of the power poles and will trip under an open SCR condition.
- Low Current
- The S611 has low current protection that will trip if the average RMS current falls below a present value. The low current protection can be programmed as a percent of motor FLA from 0% to 100%.
- Low Voltage
- The S611 has low voltage protection that will trip if the average RMS voltage falls below a present value. The low voltage protection can be programmed as percent of nominal voltage from 1% to 99% with a trip delay of 0.1 to 60 seconds.
- High Voltage
- The S611 has high voltage protection that will trip if the average RMS voltage is greater than a present value. The high voltage protection can be programmed as percent of nominal voltage from 101% to 120% with a trip delay of 0.1 to 60 seconds.
- Monitoring Capabilities
- Monitoring
- The S611 has an impressive array of system monitoring capabilities that allow users to access real time process and diagnostic data. This data can be viewed at the device with the UI or through a communications network. Data over a communications network can provide valuable insight into the condition of the equipment and processes. Maintenance and production personnel can monitor critical operational and maintenance data from a central control station that can be located far away from the production facility. Process data can be monitored to determine system anomalies that may indicate a need for preventive maintenance or an impeding failure.
- When faults occur, real time fault data can assist maintenance in troubleshooting and planning repair resources. Remote reset signals can be given to tripped devices without the need for manual intervention by maintenance personnel.
- Average Line Current
- Provides the average of the three phase MS line currents in amps, accurate to within 2%. Current data can be used to indicate a need for maintenance. Increased currents in a fixed load application can indicated a reduction in a system efficiencies and performance, signifying system maintenance is due.
- Average Pole Current
- Provides the average of the three phase RMS pole currents in amps accurate to within 2%. The pole current is the current through the soft starter. The line and pole current will be identical in in-line applications, and will differ in inside-the-delta applications.
- Average Line Current as a % FLA
- Provides the average RMS line current as a percentage of the S611 FLA setting.
- Three-Phase Line Currents
- Provides three RMS phase line currents in amps, accurate to within 2%. Imbalances or changes in the relative phase current to one another can indicate anomalies in the motor or electrical distribution system.
- Three-Phase Pole Current
- Provides three RMS phase pole currents in amps, accurate to within 2%. The pole current is the current through the soft starter. The line and pole current will be identical in in-line applications.
- Three-Phase Line Voltages
- Provides the individual RMS three phase line voltages. Imbalances or changes in the relative phase voltage to one another can indicate anomalies in the motor or electrical distribution system. Voltages can be used to monitor electrical distribution system performance. Warnings, alarms and system actions to low or high voltage conditions can be implemented.
- Percent Thermal Memory
- Provides the real time calculated thermal memory value. The S611 calculates thermal memory value. A 100% value represents the maximum safe temperature of the motor. When the thermal memory value reaches 100$, an overload trip will occur, removing power to the motor.
- The thermal memory value can be of great use in determining an impeding overload trip condition. Alarms can be implemented in the process monitoring system warning of an impeding trip before a trip occurs, halting the process. Costly system downtime can be avoided.
- Pole Temperature
- Increase in pole temperature are caused by increase in ambient temperature, start/stop time and start duty cycles. Changes in pole temperatures represent a change in system operating conditions. Identifying unexpected operating conditions or changes can prompt maintenance and aid in process evaluation activities.
- Diagnostics
- Fault Queue
- Current fault and a fault queue containing the last nine system faults can be read through the UI or communications network. Fault identification can minimize troubleshooting time and cost and prevent arc flash incidents. The fault queue can be remotely accessed through a communications network to assist in planning maintenance resources. 30 different faults can be identified by the S611.
- Control Status
- The S611 provides data that represents system conditions that can be read through the UI or the communications network. This data identifies the status of the system and the control commands the system is requesting of the S611. This can be used for advanced troubleshooting and system integration activities.
