Specialized Enclosures for Harsh Environments
We offer disconnects in various NEMA-rated enclosures to withstand the most demanding industrial conditions:
NEMA 1 & 12: Indoor use; protects against dust, lint, and dripping liquids.
NEMA 3R: Outdoor use; rainproof and sleet-resistant.
NEMA 4X (Stainless Steel): Maximum corrosion resistance for Wastewater and Food Processing sites.
NEMA 7/9 (Explosion-Proof): Cast aluminum enclosures designed for Class I & II, Division 1 & 2 hazardous locations (Oil & Gas).
Key Features for Industrial Reliability
Visible Blades: Allows for quick visual confirmation that the circuit is disconnected.
Quick-Make/Quick-Break Mechanism: Ensures consistent contact operation, extending the life of the switch and reducing arc flash risk.
Dual-Cover Interlock: Prevents the door from being opened when the switch is "ON" and prevents the switch from being turned "ON" while the door is open.
Padlockable Handles: Meets OSHA lockout/tagout (LOTO) requirements for worker safety.
Applications
Motor Isolation: Local disconnect for pumps, fans, and conveyor belts.
HVAC Systems: Safe disconnection for rooftop units and chillers.
Oil & Gas Infrastructure: Reliable power isolation in classified hazardous areas.
Manufacturing Lines: Emergency shutdown and maintenance isolation for heavy machinery.
