Motor Protector MS116-4.0 2.5-4A

Manual motor starters are electromechanical protection devices for the main circuit. They are primarily used to manually start and stop motors and provide less protection than fuses against short circuits, overloads, and phase failures. Reduced fuse protection saves costs and space and ensures a quick response to short circuits by shutting off the motor in milliseconds. Starter combinations are equipped with contactors. The equipment features manual control/short circuit and overload current protection, with adjustable current settings for load protection and magnetic trip indication. It includes a disconnection function, temperature compensation, remote control via minimum voltage release and shunt trip, and a short circuit breaking capacity (Ics) of up to 100 kA. The specific reference 1SAM250000R1008 is a motor protection circuit breaker. Its features are: Overload release current setting: 2.5 - 4 A, Instantaneous short circuit release range: 50A, With thermal protection, Phase failure sensitive, Release technique: Thermomagnetic, Rated operating voltage: 690V, Rated continuous current Iu: 4A, Rated operational power at AC-3, 400 V: 1.5kW, Main circuit connection type: Threaded connection, Actuator element design: Rotary knob, Device construction: Complete device in housing, Number of poles: 3.
