BHZ51 Explosion Proof Switch 220V380V 10A-100A Die-Cast Aluminum

Explosion-Proof BHZ51 Wall Mount Control Switch for Hazardous Locations – Aluminum Housing & Stainless Steel Exterior

The BHZ51 Explosion-Proof Switch is a reliable, industrial-grade control switch engineered for use in hazardous environments where ignitable vapors, gases, dust, or corrosive elements are present. Designed for wall-mount installation, this model offers superior safety, durability, and performance in demanding industries such as oil & gas, chemical processing, pharmaceuticals, wastewater treatment, and pulp & paper production.

Application & Working Principle

The BHZ51 control switch is built to withstand frequent on/off cycles without warm-up time, making it ideal for areas that demand fast, energy-efficient power cycling. This product ensures uninterrupted performance in zones with high humidity, volatile gases, or corrosive air. It effectively prevents ignition of explosive atmospheres by containing sparks or arcs within its explosion-proof enclosure.

Its robust design also helps reduce long-term maintenance costs, making it an excellent choice for high-risk industrial settings that require enhanced safety compliance and operational efficiency.
