Eaton Specification Sheet - CB1633T120480E
CB1633T120480E delivers a robust protection profile for demanding installations. High amperage rating at 1600A and a 480V supply with a 120V control circuit support heavy motor feeders and large process equipment, while the three-pole, three-wire topology enables clean integration into standard switchgear enclosures. This design reduces nuisance trips and short outages by providing precise coordination with upstream devices. An Arc Energy Reduction Relay minimizes arc flash energy during faults, improving safety for maintenance crews and reducing equipment damage, downtime, and repair costs. Included matched CTs and a dedicated control power transformer simplify wiring, accelerate commissioning, and improve protection accuracy across the drive and feeder network. Fusible protection, UL Listed certification, and top-feed configuration together offer regulatory compliance, safer audits, and durable performance in industrial environments. With dimensions of 16 in L, 28 in H, 24 in W and a weight of 175 lb, the unit supports rugged field deployment while leaving space for cable terminations and future upgrades.
