Motor Protector MS116-6.3 4.0-6.3A

Manual motor protectors are electromechanical protection devices for the main circuit. They are primarily used to manually start and stop motors and offer less fuse protection against short circuits, overloads, and phase failures. Reduced fuse protection saves costs and space, ensuring a quick response to short circuits by shutting down the motor in milliseconds. Starter combinations are equipped with contactors. The equipment features manual control/short-circuit and overload current protection, adjustable current settings for load protection, magnetic trip indication, disconnection function, temperature compensation, remote control via undervoltage release, and shunt trip, with short-circuit breaking capacity (Ics) up to 100 kA. The reference 1SAM250000R1009 specifically refers to a motor protection circuit breaker. Its characteristics are: Overload release current setting: 4 - 6.3 A, Instantaneous short-circuit release setting range: 78.8A, With thermal protection, Phase failure sensitive, Release technique: Thermomagnetic, Rated operating voltage: 690V, Rated continuous current Iu: 6.3A, Rated operational power in AC-3, 400 V: 2.2kW, Main current circuit connection type: Screwed connection, Actuator element execution: Rotary knob (handle), Device construction: Complete device in enclosure, Number of poles: 3.
