Air/gas circuit breakers - Megger

Sulfr hexafluoride circuit breakers suffer less wear on the main contacts than do air and oil circuit breakers. The breaking principle is to cool down the arc by blowing Sulfr hexafluoride gas with high pressure towards the arcing contacts. An sf6 gas circuit breaker’s arc extinction method may be characterized as either puffer or self-blast.Get price

Circuit breaker - Wikipedia

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household applGet price
