BXJ-IIB Series Explosion-proof Terminal...
- ◆ Constructed with a high-strength copper-free aluminum alloy, this explosion-proof terminal boxes ensures safety by containing internal explosions and isolating the external hazardous atmosphere.
- ◆ The explosion proof enclosures 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 IP66 rating prevents internal component of the ex terminal boxes aging and corrosion, which extends system life and lowers maintenance costs.

FAQ
- Q1: What are the principles of explosion-proof terminal boxes?
- A: They are based on Flameproof (Ex d) to cool flames and reduce pressure, and Increased Safety (Ex e) to prevent arcs/sparks.
- Q2: Do the terminal boxes need regular maintenance?
- A: Yes; critical checks include inspecting flameproof surfaces, ensuring tight fasteners, and replacing damaged 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 strictly comply with electrical standards.
- Q4: Is it fully waterproof/dustproof?
- A: Yes, with an IP66 rating, it is designed to resist powerful water jets and dusty conditions for reliable outdoor protection.
