Built-in Bypass Relay and Smooth Motor Starts/Stops

Achieved in a Compact Starter

• Advanced functions include soft start, kick start, and soft stop.

• Phase control using a thyristor limits current when the motor starts, and a

• Controls 3-phase, 3-wire motor or 3-phase, 6-wire motor.

• Built-in electronic thermal overload relay.

• Built-in fault diagnosis for overtemperature, phase reversal, phase loss/open

• cULus listed; complies with IEC standards.

• Mounts with screws or to DIN track.

• Built-in operation/fault indicator.

• Built-in auxiliary contact for fault indication.

• Built-in auxiliary contact to output operating status.

• An Optional Auxiliary Contact Block can be added to output operating status.
