FAQs
The EIBB3100 uses an EG frame with a bolted/ground joint enclosure, designed for three-pole mounting in hazardous locations. Its copper-free aluminum enclosure provides corrosion resistance, while the bolted joint simplifies sealing and field servicing. Compatible with other EIB series components to streamline interlocks and panel integration.
Rated at 100 A and 600 Vac with a three-pole configuration, the EIBB3100 delivers reliable protection for feeders and motors in hazardous zones. While trip curves vary by device version, its robust EG frame construction supports stable operation under typical industrial fault conditions, aligning with NEC/CEC requirements for high-integrity protection.
Ideal for oil and gas, chemical processing, and other process industries operating in hazardous locations, the EIBB3100 provides compliant circuit protection for feeders, distribution panels, and motor control centers. Its explosionproof rating and rugged aluminum enclosure support long service life in harsh environments.
The EIBB3100 carries NEC/CEC standards compliance with hazardous-location ratings including Class I, Division 1/2 and Zone 1/2, plus NEMA ratings 3, 3R, 4, 7, 9. These certifications facilitate code-compliant installations and simplify audits across North American facilities.
Investing in the EIBB3100 yields durability and lower lifecycle costs due to copper-free aluminum construction and a bolted/ground joint enclosure that resists corrosion. Availability of documentation (IF1501 instruction sheet, spec sheets, 3D models) speeds commissioning, reduces downtime, and improves overall return on investment over traditional metal breakers.
