Explosion-proof circuit breakers are used in hazardous locations where flammable gases and dust are present. They can prevent arcs, sparks, and high temperatures that can cause flammable gases and dust in the surrounding environment from occurring in explosion-proof circuit breakers. They can then reach explosion-proof lighting fixtures. Different flammable gas mixture environments have different requirements for the explosion-proof grades and explosion protection methods of explosion-proof lamps. Specific reference GB3836, IEC60079.
Explosion-proof circuit breaker features 1, explosion-proof circuit breaker cast aluminum alloy shell, surface spray,. Explosion-proof anti-corrosion circuit breaker for plastic injection molding, explosion-proof circuit breaker built 2, explosion-proof circuit breaker built-in high-breaking miniature circuit breaker or low-voltage molded case circuit breaker.
3, explosion-proof circuit breaker has overload, short circuit protection function, can also be installed according to demand.
4, explosion-proof circuit breaker leakage shunt tripping and other protection equipment.
5, explosion-proof circuit breakers or cable wiring can be.
6. Add indicator button according to the requirements. Applicable scope Zone 1 and Zone 2 Risk Locations IIA, IIB, and IIC Explosive Gas Environment Flammability Dust Environment Zone 20, Zone 21, Zone 22 The temperature zone is T1-T6. Application scope of circuit breakers Group Meaning 1.1 Blasting gas The different countries and regions with different risk environments have different blasting risk areas according to their own specifications. According to the repeated degree and duration of blasting gas mixture presented in China, explosion-proof circuit breakers divide blasting gas environment into Zone O, Zone 1 and Zone 2. (with IEC World Electrotechnical Commission)
Zone 0: The environment in which blasting gas mixtures are presented or presented for a long time.
Zone 1: The environment in which explosive gas mixtures can be present during normal operation.
Zone 2: The environment in which blasting gas mixtures cannot be present during normal operation or even the environment in which only a short-lived blasting gas mixture is present.
Zone 0 generally exists only in sealed containers, explosion-proof circuit breaker tanks and other internal gas spaces, and is rarely present during the internship program. Most of the conditions are attributed to Zone 2.
1.2 explosion-proof electrical equipment is divided into two categories:
Category I electrical equipment for underground mines Class II electrical equipment for applications other than mines Class II electrical equipment, according to its applicable to the largest experimental safety void or minimum current ratio of blasting gas mixture, is divided into IIA, IIB, IIC Three types; and according to its maximum surface temperature is divided into six groups T1-T6.
