Motor Protector MS132-0.4 0.25-0.4A

Manual motor protectors are electromechanical protection devices for the main circuit. They are primarily used to manually start and stop motors and to provide less protection than fuses against short circuits, overloads, and phase failures. Reduced fuse protection saves costs, space, and ensures a quick reaction to short circuits, as it shuts off the motor in milliseconds. Starter combinations are equipped with contactors. The equipment features manual control / protection against short-circuit currents and overloads, adjustable current setting for load protection, and magnetic trip indication, with disconnection function, temperature compensation, remote control via minimum voltage release, shunt trip, and short-circuit breaking capacity (Ics) up to 100 kA. The reference 1SAM350000R1003 specifically refers to a motor protection circuit breaker. Its features include: Overload release current setting: 0.25 - 0.4 A, Instantaneous short-circuit release setting range: 5A, With thermal protection, Phase failure sensitive, Release technique: Thermomagnetic, Rated operating voltage: 250 - 690 V, Rated continuous current Iu: 0.4A, Rated operational power in AC-3, 400 V: 0.09kW, Main circuit connection type: Threaded connection, Actuator element execution: Rotary button (handle), Device construction: Complete device in housing, Number of poles: 3.
