Breaker Integrated Transformer (BIT)
Eaton’s Breaker Integrated Transformers (BIT) integrates a traditionally separate Molded Case Circuit Breaker (MCCB) and a low-voltage dry-type distribution transformer. Factory-assembled and fully tested, BIT helps reduce arc-flash hazard, footprint and overall cost of the electrical distribution system.
Primary, secondary, primary-secondary, and secondary-secondary
Aluminum or copper
Includes transformers with DOE 2016 and NEMA TP-1 efficiency requirements, and transformers with other efficiency requirements
Replace the need for separate power distribution components with a fully enclosed molded-case circuit breaker (MCCB) integrated into Eaton’s proven low-voltage dry-type distribution transformer technology
Available in 150°, 115°, and 80° C
Take advantage of space savings with an integrated design that can save up to 30 percent compared to traditional, separately installed solutions
Easily configure to specific application needs with a wide range of primary, secondary, primary and secondary, or secondary and secondary breaker choices
Reduce hazard of arc flash
Transformers include a versatile bonding/grounding bar affixed to the bottom panel as standard, to provide compliance with NEC 450.10(A)
