CA3100W - 100Amp Circuit Breaker

CA3100W - 100Amp Circuit Breaker

The CA3100W circuit breaker is a 100 amp, 3 pole molded case breaker used in commercial and industrial electrical distribution systems. Built for Type CA applications, it features a non-interchangeable trip unit and a 10kA interrupting rating at 240VAC. Whether you're replacing an existing breaker or maintaining installed equipment, matching the correct ratings and configuration is critical—and that's exactly where the CA3100W fits.

With its compact footprint and molded case construction, this breaker is commonly found in switchboards, panelboards, and other power distribution equipment. Rated for operation in ambient temperatures up to 40°C (104°F), it helps protect circuits and connected equipment from overcurrent conditions while maintaining compatibility with existing Type CA systems.
