100S-D250EJ22C

The Allen-Bradley 100S-D250EJ22C device is a contactor. A contactor is a special kind of relay that is used for switching electrical circuits in a system. Contactors are commonly used for applications involving lighting and motors. The 100S-D250EJ22C contactor is a safety contactor which is part of the Allen-Bradley 100S-D series. It is rated for 250 Amps of operational current at 60 degrees Celsius and 400 Volts and for 350 Amps of current at 40 degrees Celsius and 690 Volts. There are 2 normally closed and 2 normally open contacts on the 100S-D250EJ22C contactor. It can be used for switching AC motors rated at up to 250 Horsepower at 575 Volts AC and 60 Hertz frequency and at up to 250 kilowatts at 500 Volts  AC and 50 Hertz frequency. To prevent electric shock, Allen-Bradley recommends disconnecting the power to the contactor when it is under maintenance.

The Allen-Bradley 100S-D250EJ22C contactor features a safety design which prevents state change for normally closed auxiliary contacts if and when a power contact on the contactor welds due to high current levels. This design is called the mirror contact design. This safety feature is designed to provide a reliable indication about the open or closed status of the main power poles on the contactor. The 100S-D250EJ22C contactor is a 3-pole device which is available in compact dimensions. A PLC interface is integrated into the 100S-D250EJ22C contactor. Other features of the contactor include a low power pick-up and hold-in function and support for a wide voltage range. The 100S-D250EJ22C contactor features an electronically controlled coil. The weight of the contactor is approximately 7.5 kilograms.
