Explosion-Proof Junction Box

Explosion-proof junction boxes are special equipment used in various high-risk environments. Compared to civilian junction boxes, they are modified through various explosion-proof measures to achieve explosion-resistant functionality.

Introduction

Explosion-proof junction boxes are special equipment used in various high-risk environments. Compared to civilian junction boxes, they are modified through various explosion-proof measures to achieve explosion-resistant functionality.

Categories

They are manufactured using die-cast aluminum alloy or welded stainless steel. Explosion-proof and corrosion-resistant junction boxes can be classified as follows: by function, material, and form—intrinsically safe explosion-proof junction boxes, aluminum alloy explosion-proof junction boxes, stainless steel explosion-proof junction boxes, and steel plate explosion-proof junction boxes; by usage structure—wall-mounted explosion-proof junction boxes and freestanding explosion-proof junction boxes.

Scope of Application

1. Zone 1 and Zone 2 hazardous gas environments;

2. Gas or vapor environments of Class IIA, IIB, IIC, Groups T1-T5;

3. Indoor and outdoor use (IP54, IP65* must be specified when ordering).

Technical Features
1. Explosion-proof junction boxes are used in circuits below 380V for wiring and branching of various electrical equipment.
2. Materials include glass fiber unsaturated resin, stainless steel, and cast aluminum alloy housing with surface coating, offering an aesthetically pleasing appearance.
3. Explosion-proof junction boxes feature a labyrinth sealing structure, providing excellent waterproof and dustproof performance.
4. Modular design allows for unlimited terminal numbers, cable entry/exit directions, and quantities, meeting various user requirements.
5. Compatible with conduit or cable wiring.
6. Explosion-proof junction boxes comply with GB3836-2000, IEC60079, GB12476.1-2021, and IEC61241 standards.
