BXM(D) Series Explosion-Proof Distribution Box
Explosion-proof lighting (power) distribution box with a composite structure: the main chamber is flameproof (Ex d) and the terminal chamber is increased safety (Ex e). The modular design lets all circuits be freely combined, and the built-in high-breaking MCB or moulded case circuit breaker is operated by the handle on the cover.
