Quick Summary

The EID disconnect switch is a rugged isolation device designed for safe power shutdown in hazardous locations such as oil, gas, and chemical facilities. This addresses the challenge of finding a durable, compliant switch that survives harsh environments while delivering reliable operation. It carries critical certifications that matter in validation and commissioning: NEC/CEC compliance, Class I Division 2, and Zone ratings, plus NEMA 4X/7/9 protection for outdoor and rugged installations. In addition to safety, the unit offers a copper-free aluminum enclosure and an external epoxy powder coat finish that resist corrosion in aggressive atmospheres. For panel builders and maintenance teams, the combination of rugged construction and certified reliability translates into faster commissioning, reduced downtime, and a smoother road to compliance.

Feature: Amperage and horsepower versatility enables a single switch to cover multiple motor sizes, reducing spare parts and inventory. Impact: Streamlined procurement and faster replacements, lowering total cost of ownership. Application: Suitable for pumps, fans, and conveyors in hazardous environments where 5 to 30 HP motors are common. Feature: Copper-free aluminum enclosure with external epoxy powder coat provides excellent corrosion resistance and a lighter footprint. Impact: Longer service life in aggressive atmospheres with easier handling during installation and maintenance. Application: Outdoor or chemically challenging installations where protective finishes matter. Feature: Auxiliary contact (single block) supports interlocks and PLC/SCADA signaling. Impact: Simplified control wiring, improved safety interlocks, and enhanced automation capability. Application: System interlocks and remote monitoring in hazardous locations. Feature: Non-fused design paired with a switch enclosure enables straightforward disconnection and safer startup sequences. Impact: Reduced thermal stress on upstream circuits and simplified startup logic. Application: Industrial equipment shutdowns in hazardous zones where rapid isolation is required. Feature: Compact form factor with 10.47 in length, 12.47 in height, and 9.65 in width (36 lb) offers practical installation in restricted spaces. Impact: Less enclosure footprint, easier retrofits, and cost-effective mounting options. Application: Instrument rooms, racks, and outdoor installations where space is at a premium. Feature: Compliance with NEC/CEC and hazardous-location ratings (Class I, Division 2; Zone 1/2; Class II Division 1; Class III) and NEMA protections (4X, 7, 9). Impact: Faster regulatory approval, reduced risk of non-compliance, and safer operation in demanding environments. Application: Global industrial settings requiring robust hazardous-location certification and enclosure protection.
