Motor protector MS116-6.3 4.0-6.3A

Manual motor protectors are electromechanical protection devices for the main circuit. They are mainly used to start and stop motors manually and to provide less protection to 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 down the motor in milliseconds. Starter combinations are equipped with contactors. The equipment features manual control / protection against short circuit currents and overloads, the current setting is adjustable for load protection, and it has a magnetic trip indication, disconnection function, temperature compensation, remote control via minimum voltage release, and short circuit breaking capacity (Ics) up to 100 kA. The reference 1SAM250000R1009 specifically refers to a motor protection circuit breaker. Its characteristics are: Adjustable overload release current: 4 - 6.3 A, Instantaneous short circuit release adjustment range: 78.8A, With thermal protection, Sensitive to phase failure, Release technique: Thermomagnetic, Rated operating voltage: 690V, Permanent rated current Iu: 6.3A, Rated operating power in AC-3, 400 V: 2.2kW, Main circuit current connection type: Threaded connection, Actuator element design: Rotary button (control), Device construction: Complete device in housing, Number of poles: 3.
