CA3100 - 100Amp Circuit Breaker

CA3100 - 100 Amp Circuit Breaker

The CA3100 circuit breaker is a 3-pole, 100 amp molded case circuit breaker designed to provide dependable overcurrent protection in commercial and industrial electrical distribution systems. Built on the CA frame and rated for 10,000 A.I.C. at 240VAC, this breaker is engineered for use in 40°C ambient environments and features a non-interchangeable trip unit for consistent, factory-calibrated protection. Supplied with both line and load-side lugs, the CA3100 is ready for straightforward installation in compatible panelboards and switchgear. For facilities maintaining or servicing existing CA-frame systems, this breaker offers proper form, fit, and function to keep equipment operating safely and efficiently.

Designed with durability in mind, the CA3100 molded case circuit breaker helps protect conductors and equipment from overloads and short circuits. Its solid construction and dependable trip characteristics make it a practical solution for maintaining legacy electrical systems where compatibility and accurate ratings matter most.
