Eaton EBMX1B-W100 Explosionproof Circuit Breaker - Class I
Part Number: EBMX1B-W100
Quick Summary
Eaton EBMX1B-W100 is a clamped explosionproof circuit breaker for hazardous locations in industrial power distribution. Engineers often struggle to source a compliant unit that installs quickly, withstands harsh environments, and remains serviceable over the plant’s lifetime. This model delivers NEC/CEC compliance along with Class I, Division 1 and Zone 1 ratings, and NEMA 3R/4X protection for outdoor or corrosive environments. The copper-free aluminum enclosure reduces weight and corrosion risk while maintaining rugged mechanical integrity. With a 600 Vac rating and three poles, it supports motor starters and power-distribution needs, enabling safer, more reliable installations and lower total cost of ownership.

FAQs
Yes. EBMX1B-W100 is designed for EBMXB system compatibility and ships with a Size 1 enclosure. The clamped enclosure enables straightforward sealing and service access, while the three-pole configuration matches common hazardous-location starter and feeder applications. Mounting typically follows standard enclosure practices for Size 1 housings, with appropriate fasteners and gaskets to maintain the integrity of the explosionproof rating.
The breaker is rated for 600 Vac with a 100 AIC interrupt rating and a three-pole configuration. These specifications support high-demand motor control and robust fault protection in hazardous environments, aligning with NEC/CEC requirements for safety-critical applications.
Designed for Hazardous/Classified Locations, the EBMX1B-W100 carries NEC/CEC standards and Class I Division 1 Zone 1 ratings, along with compatible NEMA ratings. It is suitable for oil and gas, chemical processing, mining, and other environments requiring explosionproof protection for electrical distribution and control circuits.
This model meets NEC/CEC standards and is rated for Hazardous Locations (Class I, Division 1 and Zone 1, as well as Division 2 and Zone 2) with compatible NEMA ratings (3R, 4X, 7, 9). These certifications help streamline approvals and ensure regulatory alignment across multinational sites.
The copper-free aluminum enclosure reduces corrosion risk and weight, improving handling and longevity in tough environments. Clamped construction simplifies field servicing, reducing downtime. Combined with NEC/CEC compliance and rugged NEMA protection, this translates to lower maintenance costs and a lower total cost of ownership over the device’s lifecycle.
