Information about ABB Motor Protection Switch MS116 690 V AC 1 A
Manual motor protectors are electromechanical protection devices for the main circuit. They are primarily used to manually start and stop motors and to provide fuses with less protection against short circuits, overloads, and phase failures. Lesser fuse protection saves costs, space, and ensures a quick reaction 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. It has disconnection function, temperature compensation, remote control via undervoltage release and shunt trip, and a short circuit breaking capacity (Ics) of up to 100 kA. The reference 1SAM250000R1005 specifically refers to a motor protection circuit breaker. Its characteristics are: Overload release current setting: 0.63 - 1 A, Instantaneous short circuit release setting range: 12.5A, With thermal protection, Phase failure sensitivity, Release technique: Thermomagnetic, Nominal operating voltage: 690V, Continuous nominal current Iu: 1A, Nominal operating power in AC-3, 400 V: 0.25kW, Main circuit connection type: Threaded connection, Actuator element execution: Rotary button (handle), Device construction: Complete device in housing, Number of poles: 3.
