BXJ 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: Based on two main types: Flameproof (Ex d), which uses precision gaps at joints to cool flames, and Increased Safety (Ex e), which prevents 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 damaged parts with original factory spare parts.
- Q3: Can internal wiring be connected carelessly after installation?
- A: Absolutely not. The box only provides “containment,” and all internal electrical connections must strictly comply with electrical standards.
- 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 for reliable protection.
