S811+T18N3S

The S811+T18N3S soft starter is a 3-pole S811+ series non-combination soft starter manufactured by Eaton. Its specifications are 180 Amps of current, 50 to 150 Horsepower or 51 to 100 kilowatts of output power, 200 to 600 Volts AC voltage, and 60 Hertz frequency. Its width, height, and length are 7.65 inches, 12.71 inches, and 6.47 inches, respectively. It has a 200-millimeter frame and it features 2 separate ramp profiles to accommodate the variations in the starting requirements of different applications. Apart from voltage ramp start, the S811+T18N3S soft starter offers other startup options to achieve smooth acceleration and deceleration during motor startup and when the motor is powered down. The S811+T18N3S soft starter has built-in communication capabilities that are accessible through its communication port. Its parameters can be configured locally through its removable digital interface module. Its 3-pole design and built-in motor wiring parameters give the users access to 2 different motor wiring configurations to choose from. The S811+T18N3S soft starter provides a reliable solution for ensuring that drives which are used to power industrial mixers, conveyor belts, mills, or circular band saws in motion systems function as efficiently as possible. The powerful diagnostics and protective components of the S811+T18N3S soft starter ensures optimum performance throughout its run sequence by monitoring and promptly reporting potential fault conditions through the digital interface module, over the network or through alarms. The thermal condition of each of the 3 poles on the S811+T18N3S soft starter can be monitored via the DIM in real-time to avoid excessive temperature conditions, and this module can be door or device-mounted.

The S811+T18N3S is a soft-starter device that is manufacture by Eaton. It is mainly used to implement smooth start-up and stopping of motors, minimizing the mechanical stress from being experienced by the motor. It is also used to lower energy consumption as proper implementation of start-up and stopping functions will result to lesser production of inrush current. This is a microprocessor based Soft-starter with fully programmable functions including Kick start, Current Limit Start, Soft Stop, and Pump Stop.

The S811+T18N3S is provided with an internal Thermal Overload. This protects the motor from excessive heat, produced during generation of high-level of current over an extended period of operation. This built-in protection prevents damage from the motor itself and the power wiring. Other integrated motor protection to the S811+T18N3S includes Incoming Line Phase Reversal, Loss, Imbalance, Over Voltage, Under Voltage trips, three (3) Overcurrent trips, and Stall and Jam trips.

The S811+T18N3S comes with an embedded Digital Interface Module (DIM) with LCD display and pre-defined function keys for local and remote configuration, monitoring and operation of the soft starter, Modbus communication interface for integration to higher level control systems, built-in Input and Output terminals and Local (SH1) and Remote (CH0) QCPort Network control ports.

The S811+T18N3S is used with 3-Phase motors. It has a Main Supply Voltage of 200–600 Volts AC and Control Voltage of 24 Volts DC while the rated operational current is 180 Amperes (AC-53) and 311 Amperes (AC-53, In-Delta) with an output power of 150 Horsepower. This starter is a Frame T device.
