The shell of BDZ52 explosion-proof circuit breaker is made of aluminum alloy high pressure casting, and the surface is sprayed with high voltage electrostatic plastic after shot blasting. This series of products is a composite structure, the main cavity adopts flameproof structure, the connecting cavity adopts increased safety structure.
First, BDZ52 explosion-proof circuit breaker application scope:
1, suitable for explosive gas environment zone 1, zone 2;
2, suitable for combustible dust environment 20, 21, 22 zones;
3, suitable for IIA, IIB, IIC explosive gas environment;
4, suitable for temperature group T1-T6/T5 environment;
5, suitable for oil refining, storage, chemical industry, medicine, textile, printing and dyeing, military and military facilities and other explosive dangerous environment;
6, overload, short circuit, under voltage protection, under normal circumstances on and off electrical devices and lighting circuits;
7, can be selected according to customer requirements with leakage protection function.
Second, BDZ52 explosion-proof circuit breaker product features:
1, the shell is made of aluminum alloy high pressure casting molding, the surface after shot blasting high pressure electrostatic spray;
2, this series of products for the composite structure, the main cavity using flameproof structure, connecting cavity using increased safety structure;
3, built-in high-break miniature circuit breaker or plastic-case circuit breaker, through the operation of the handle on the shell cover to achieve closure;
4, overload, short circuit, under voltage protection, but also under normal circumstances do not frequently switch off electrical devices and lighting circuits;
5, distribute power and protect the line and power equipment from overload, short circuit, undervoltage and other faults, but also as the motor infrequent start and short circuit, undervoltage protection;
6, steel pipe or cable wiring;
