Circuit Breaker

The Square D Powerpact R-frame molded-case circuit breaker has a standard amperage-rating range to 3,000 A.

These breakers can replace bulkier, more expensive, insulated case breakers in less space. The devices are offered with 80 and 100% ratings and interrupting ratings of 35, 65, and 100 kA at 480 Vac. The breakers are available in unit-mount models with 600 to 3,000-A ratings and I-line models up to 1,200 A. The breakers come with a RL3TB terminal kit for busing or optional cable lugs.
