Low-voltage transformers

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.
