offer Min Circuit Breaker MCB

Description

Applications and functions

1. Incoming and outgoing function in distribution systems
2. Switching and protection devices for motors, transformers and capacitors
3. Disconnect or units with features for stopping and switching off in an emergency mechanisms and terminal covers in conjunction with likeable rotary operating.
4. Available in the following versions.
5. Powe protection: the overload and short-circuit releases are designed for the protection of calbe, leads and non-motor loads.
6. Motor protection: the overload and short-circuit releases are designed for optimized protection and direct-on-lin starting of induction squirrel-cage motors. The circuit breakers for motor protection are susceptible to phase failure and feature an adjustable trip class.
