1. Explosion-Proof Maintenance Power Socket Box

1. Explosion-Proof Maintenance Power Socket Box

This product features a ZL102 aluminum alloy die-cast enclosure with corrosion-resistant stainless steel fasteners and a surface treated with high-voltage electrostatic powder coating. Its modular design allows each circuit to be flexibly assembled, offering a variety of socket specifications to meet maintenance power requirements. It comes equipped with overload and short-circuit protection functions, and can be customized with leakage protection and a main switch upon request.
Before installation, ensure the nameplate specifications match the intended usage. Power must be disconnected during installation or maintenance. When disassembling for maintenance, avoid striking or scratching the flameproof surfaces, and periodically apply 204-1 anti-rust oil. Routine inspection is recommended to ensure proper operation.

Note: Only qualified professionals may open the enclosure for maintenance or inspection.
