MCCB Motor Operator — What It Is
The ABB 1SDA073722R1 is a motor operator intended for use with ABB Molded Case Circuit Breakers (MCCB). It provides remote electrical open/close control of the breaker, typically used in motor control centers or distribution panels where the breaker needs to be cycled from a PLC or SCADA system without an operator pulling the handle.
The part is listed under the Motors category, but functionally it is a control accessory for a circuit breaker, not a standalone motor.
