Motor Protector MS165-25 18-25A

Manual motor starters are electromechanical protection devices for the main circuit. They are primarily used for manually starting and stopping motors and provide less protection than fuses against short circuits, overloads, and phase failures. Reduced fuse protection saves costs, space, and ensures a swift response to short circuits, as it shuts down the motor in milliseconds. Starter combinations are equipped with contactors. The equipment features manual control / protection against short-circuit and overload currents, adjustable current settings for load protection, and magnetic trip indication, with a disconnection function, temperature compensation, remote control via minimum voltage release, and shunt trip and short-circuit breaking capacity (Ics) up to 100 kA. The reference 1SAM451000R1013 specifically refers to a motor protection circuit breaker. Its features include: Overload release current setting: 18 - 25 A, Instantaneous short-circuit release adjustment range: 375A, With thermal protection, Phase failure sensitive, Release technique: Thermomagnetic, Rated operating voltage: 250 - 690 V, Permanent rated current Iu: 25A, Rated operating power in AC-3, 400 V: 11kW, Main current circuit connection type: Threaded connection, Actuator element execution: Rotary button (control), Device construction: Complete device in housing, Number of poles: 3.
