Explosion-proof circuit breaker refers to the dangerous place for flammable gases and dust, can prevent the explosion-proof circuit breaker may produce arc, spark and high temperature ignition of flammable gases and dust in the surrounding environment, so as to meet the explosion-proof requirements of the lamp, different flammable gas mixture environment for explosion-proof lamp explosion-proof grade and explosion-proof form have different requirements.
Explosion-proof circuit breaker features 1, explosion-proof circuit breaker cast aluminum alloy shell, surface spray plastic. The explosion-proof anti-corrosion circuit breaker is made of engineering plastic injection molding and is equipped with explosion-proof circuit breaker
2, explosion-proof circuit breaker is equipped with high-break miniature circuit breaker or low-pressure plastic-case circuit breaker.
3, explosion-proof circuit breaker with overload, short circuit protection function, can also be installed according to requirements.
4, explosion-proof circuit breaker leakage shunt trip and other protection devices.
5, explosion-proof circuit breaker steel pipe or cable wiring can be.
6. An indicator button can be added as required
