BXX52-2/K63/380V Explosion proof Maintenance Box

1The shell is made of aluminum alloy die-casting and the surface is coated with high-voltage electrostatic spraying; It can also be made of steel plate welding material or stainless steel material.

2Install plastic casing or miniature circuit breakers and other components inside the main chamber. An increased safety chamber is used for wiring, with surface mounted explosion-proof buttons, explosion-proof indicator lights, and explosion-proof plug sockets. Explosion proof chambers can also be installed according to customer requirements.

Explosion proof maintenance box can be used in Zone 1, Zone 2 hazardous areas or 20, 21, 22 hazardous areas; Further confirm the type of explosion-proof maintenance box through on-site gas classification. Methane (biogas), acetylene, and ethylene can use Class II B-level explosion-proof structure types, while hydrogen and acetylene must use Class II C-level explosion-proof structure types; Explosion proof maintenance boxes are divided into outdoor rainproof and explosion-proof maintenance boxes (IP65) and indoor explosion-proof maintenance boxes (IP54); The maximum temperature group level of the explosion-proof electrical equipment in the explosion-proof maintenance box is T6 (maximum surface temperature of 85 ℃).

The explosion-proof maintenance box can be used for the control and maintenance of explosion-proof electrical equipment and non explosion-proof electrical equipment. It is easy to operate and equipped with explosion-proof plugs, allowing for flexible wiring without environmental restrictions.

BXX52-2/K63/380V Explosion proof Maintenance BoxPreparation before use

1. Before installing and using the product, it is necessary to check whether the technical data on the nameplate matches the usage situation;
2. Before installation and maintenance, the front-end power supply must be cut off;
3. When the incoming and outgoing cables of the explosion-proof maintenance box pass through the rubber sealing ring, they must be tightened with washers and compression nuts to ensure that the seal and cables are not loose;
4. If the sealing ring corrodes, cracks, deforms, becomes sticky, or experiences a hardness change exceeding 20% of its original value during use, it should be promptly purchased and replaced from the manufacturer to ensure reliable explosion-proof performance;
5. During maintenance and disassembly, pay attention to the explosion-proof surface not being bumped, scratched, or corroded, and regularly apply 204-1 anti rust oil;
6. The explosion-proof maintenance box should be regularly inspected during use (at least every 15 days) to ensure its good operation;
7. Non electricians are strictly prohibited from opening covers for maintenance and inspection.
