FAQs

Eaton's EIBB3100 S146 should be installed in approved explosion-protected enclosures (EG frame) with proper grounding and secure bolted/ground joint covers. Verify compatibility with Crouse-Hinds EIB enclosures, use insulated neutral lug connections, and follow NEC/CEC guidelines for Class I/II/III and Zone 1/2 installations to maintain safe operation and regulatory compliance.
Key specs include a 100 A amperage rating, 600 Vac voltage rating, and a three-pole configuration. It uses an EG frame, comes with a bolted/ground joint enclosure, and features a copper-free aluminum housing with an insulated neutral lug to support safe, reliable protection in hazardous locations.
Yes. The unit is specified for NEC/CEC compliance and offers hazardous-location ratings compatible with Class I/II/III locations and Zone 1/2 coverage, fulfilling industry-standard safety and regulatory requirements for chemical plants, oil & gas facilities, and similar environments.
Common applications include control panels, switchgear, and motor feeders in hazardous-location facilities such as chemical processing plants, refineries, and offshore installations where explosion protection, robust isolation, and reliable UL/NEC-compliant performance are essential.
Regular visual inspections, secure mounting, and periodic fault-tripping checks help ensure reliability. The copper-free aluminum enclosure offers corrosion resistance for longer service life in harsh environments, reducing replacement frequency and lowering total cost of ownership over the asset lifecycle.
