Leading the way in EFVs

EFVs are similar to electrical circuit breakers that trip when electrical current exceeds design limits. They automatically trip when gas flow to a private residence or commercial facility exceeds design limits. This would be the case if a gas service line were to rupture because of ground movement, natural disasters or third party damage.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
