Motor Protector MS116-20 16-20A

Manual motor starters are electromechanical protection devices for the main circuit. They are primarily used to manually start and stop motors and to provide less fuse protection against short circuits, overloads, and phase failure. Less fuse protection saves costs, space, and ensures a quick reaction to short circuits by shutting down the motor in milliseconds. Starter combinations are equipped with contactors. The equipment features manual control/protection against short circuit currents and overloads, with adjustable current settings for load protection and magnetic trip indication, includes disconnection function, temperature compensation, remote control via undervoltage release and shunt trip, and short circuit breaking capacity (Ics) up to 100 kA. The reference 1SAM250000R1013 is specifically a motor protection circuit breaker. Its features are: Overload release current adjustment: 16 - 20 A, Instantaneous short-circuit release adjustment range: 300A, With thermal protection, Phase failure sensitive, Release technique: Thermomagnetic, Rated operational voltage: 690V, Rated uninterrupted current Iu: 20A, Rated operational power in AC-3, 400 V: 7.5kW, Main circuit connection type: Threaded connection, Actuating element execution: Rotary button (control), Device construction: Complete device in casing, Number of poles: 3.
