FAQs
Installation should follow the EBMB installation guides (IF 1149 variants) and the SP3D design package. Verify area classification and select the correct three-pole, 150A frame size. Use the bolted/ground joint with gasketed cover to maintain enclosure integrity and prevent ingress in Class I/II locations. Ensure proper torque on enclosure hardware and conduct final integrity checks per local codes.
The TT40TED34 is a three-pole breaker with a 150A frame size, rated for 480 Vac / 250 Vdc. Amperage range is 10 A through 70 A, with a 40 A trip configuration. This enables protection across a wide load band while maintaining safe interruption performance in hazardous environments.
Yes. The EBMB series is designed for Hazardous/Classified Locations with area classifications and NEC/CEC compliance. Its explosionproof construction, NEMA ratings (including 3, 3R, 4, 7, 9, 12), and copper-free aluminum enclosure make it appropriate for offshore platforms, refineries, and chemical processing facilities where robust protection and safety are essential.
The TT40TED34 carries NEC/CEC standards compliance and area-classification approvals for hazardous locations. NEMA ratings 3, 3R, 4, 7, 9, 12 further document enclosure performance, and there are Canadian certifications via UL for use in hazardous environments. These certifications support cross-border projects and facility-wide safety requirements.
Regular maintenance should follow Eaton’s installation instructions and recommended inspection intervals for EBMB devices. Use the provided catalogs and CAD/3D design packages to verify mounting and wiring configurations. Keep spares for common EBMB parts, inspect the gasketed cover and enclosure joints for integrity, and document any tripping events to optimize protection settings over time.
