Motor starter MS116-12A 1SAM250000R1012

Motor protection circuit breakers – reliable protection for your motors

The MS116-12A motor protection circuit breaker is a compact and efficient device designed to protect electric motors. It provides comprehensive protection against overloads, short circuits and phase failure, which translates to a longer lifespan of connected devices and minimizes the risk of failure. This 3-pole circuit breaker, only 45 mm wide, is ideal for both professional and home installations.

Solid construction and high breaking capacity

The MS116-12A is characterized by high quality and durability. The rated short-circuit breaking capacity of 50 kA at 400 V AC guarantees effective disconnection of the circuit in the event of a short circuit, protecting both the motor and the rest of the installation. The use of screw connections ensures a secure and reliable connection of the wires.

Functionality for professionals and end users

The device is equipped with a knob for manual switching on and off, which facilitates operation and maintenance. The built-in thermal protection reacts to overheating of the motor, and the phase failure sensitivity protects against damage caused by the absence of one of the supply phases. The MS116-12A circuit breaker is designed to operate in circuits with a rated voltage of 690 V AC and allows protection of motors with a power of up to 5.5 kW (for AC-3 at 400 V). Thanks to its compact dimensions (85.6 mm deep and 90 mm high), it is easy to install even in limited space. Power losses of 6.9 W minimize the impact on the energy efficiency of the system.
