Pulse-operated motor guard circuit breaker for motor protection circuits by thermal (adjustable) or short-circuit (magnetic) disconnection. Possibility of installation of front and side auxiliary contacts. High cutting capacity.

The installation of a motor circuit breaker in the power circuit of an electric motor, both three-phase and single-phase, allows to prevent breakdowns in the engine by overload, in three-phase motors, also allows to prevent breakdown in the electric motor due to loss of a phase, preventing the motor from working in 2 phases.

Types of protection:

Short circuits (Magnetic).
Overload (Thermal).
Phase failure.
