HLSW-PB20 Non-Metallic Explosion-Proof Switch C1D2/C2D2

The HLSW-PB20-PB.SG-3PSW-ESTP is a heavy-duty, non-metallic explosion-proof switch engineered for reliable motor and equipment control in hazardous Class I, Division 2 and Class II, Division 2 environments. Designed to withstand volatile industrial atmospheres, this compact station integrates high-performance switching components into a durable, corrosion-resistant housing ideal for petroleum refineries, chemical plants, and outdoor processing sites.

Built for extreme field dependability, the unit features a high-strength PA6 glass-reinforced anti-static housing with f1 UV protection and V-0 flame resistance. It operates efficiently across extreme ambient temperatures ranging from -50°C to +60°C. Equipped with silver alloy contacts, a 20A switching capacity up to 690V AC, and full silicone gasketing (NEMA 4X / IP66), it ensures long-term electrical conductivity and environmental protection during high-duty cycles.
