Its copper-free aluminum body provides corrosion resistance, while the glass cover ensures visibility for routine inspections without sacrificing protection. Ensure compliance with local hazardous-location codes and verify mounting clearance for heat dissipation.
This enclosure carries ATEX and IECEx hazardous-location certifications, along with NEC/CEC standards alignment. It is rated for hazardous/classified locations and features NEMA ratings 3, 4, 4X, 7, and 9, supporting broad international and North American deployments. Canadian certification references are available through UL, complementing the global compliance profile.
Yes. The enclosure is designed for a 3/4 inch trade size conduit with a 2 inch cover opening, which supports standard wiring and easy access for termination and maintenance. The glass cover provides visibility, and the copper-free aluminum body offers durability in harsh environments, making it suitable for many hazardous-location installations.
Ideal for explosion-protected instrumentation in oil and gas, chemical processing, mining, and wastewater treatment plants. Its ATEX/IECEx certifications, NEMA ratings, and rugged copper-free aluminum construction make it a dependable choice for protecting meters, controllers, and sensors in hazardous areas while enabling straightforward installation and service access.
Maintenance is simplified by the glass cover’s visibility and the enclosure’s corrosion-resistant copper-free aluminum. The rugged construction reduces replacement frequency, lowering lifecycle costs, while certified protection minimizes risk of regulatory noncompliance. Quick installation with 3/4 in conduit compatibility also shortens project timelines and improves total cost of ownership.
