BXJ8050-20&6 Series Junction Boxes

◆ Constructed with a high-strength GRP, this explosion-proof terminal boxes ensures safety by containing internal explosions and isolating the external hazardous atmosphere.
◆ The explosion proof enclosure treated with anti-static coating and all fasteners are anti-loosening.
◆ The explosion-proof control box provides centralized cabling and management, make the installation, maintenance, and inspection easier.
◆The IP65 rating prevents internal component of the ex terminal boxes aging and corrosion, which extends system life and lowers maintenance costs.

Q1: What are the principles of explosion-proof terminal boxes?
- A: They are based on two main types: Flameproof (Ex d), using precision gaps to cool flames, and Increased Safety (Ex e), preventing arcs/sparks through enhanced insulation.
Q2: Do the terminal boxes need regular maintenance?
- A: Yes; critical checks include inspecting surfaces for damage, ensuring tight fasteners and intact seals, and replacing parts with original factory spares.
Q3: Can internal wiring be connected carelessly after installation?
- A: Absolutely not; the box provides “containment,” but all internal connections must comply with electrical standards and all circuit equipment must be explosion-proof.
Q4: Is it fully waterproof/dustproof?
- A: This depends on the IP rating; typical boxes (such as IP66/67) resist powerful water jets or temporary immersion.
