Description
Hager Miniature Circuit Breaker B 20A 3P 6kA
Miniature circuit breaker MCB B 20A 3P 6kA MBN320E HAGER, also known as an installation circuit breaker, is a key component of an electrical system.
It protects the circuit by automatically interrupting current flow when its intensity exceeds established safety limits. It provides protection against the effects of short circuits and overloads up to 6kA. The MBN320E type B miniature circuit breaker features delayed tripping and is designed to protect devices less sensitive to thermal overloads that require low starting currents.
MBN320E circuit breaker construction:
- 1 - operating lever
- 2 - latch
- 3 - fixed contact and moving contact
- 4 - connection terminals
- 5 - thermal bimetallic release (overload)
- 6 - adjustment screw
- 7 - electromagnetic release (short circuit)
- 8 - arc chute (for arc extinguishing)
