3. This product is composite, featuring an explosion-proof structure for the switch box, an increased safety structure for the incoming and outgoing line boxes, with all cavities equipped with sealing rings for excellent waterproof and dustproof functions; the explosion-proof power distribution box is suitable for the following applications:

Power explosion-proof distribution boxes are suitable for explosive gas environments in Zone 1 and 2 hazardous areas.

2. Suitable for Class II, Groups A and B explosive gas environments.

3. Suitable for Class 21 and 22 hazardous dust environments.

4. Widely applicable to hazardous environments such as oil extraction, refining, chemical industries, and marine oil platforms, oil tankers, etc.

Features of Explosion-proof Power Distribution Box

1. This product features an explosion-proof structure with a steel plate welded housing and electrostatic powder coating on the surface.

2. Equipped with high-interrupting capacity miniature circuit breakers or molded case circuit breakers, AC vacuum contactors, motor protectors, voltmeters, and other components, featuring protection functions against overloads, short circuits, under-voltages, phase failures, and leakage currents.

3. Both incoming and outgoing lines are equipped with sparkless explosion-proof connectors, accompanied by clear equipment number indicator plates. The indicator plates are made of 304 stainless steel, bent into shape, and polished for a beautiful, practical appearance.

4. The explosion-proof face employs a special processing method, embedding oil-resistant and aging-resistant silicone "O" rings to achieve a protection grade of IP65 for the enclosure. This solves the issue of rainwater intrusion into traditional explosion-proof boxes when used outdoors, eliminating the outdated and ineffective measures such as using rain shields.

All fasteners are made of corrosion-resistant 304 stainless steel.

6. Specific features and appearance can be customized according to customer requirements.
