CA3100X - 100Amp Circuit Breaker

CA3100X - 100 Amp Circuit Breaker

The CA3100X molded case circuit breaker is a 3-pole, 100-amp breaker designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker provides consistent overcurrent protection at up to 10kA interrupting capacity at 240VAC. Rated for operation at 40°C, the CA3100X is well suited for applications where maintaining proper protection in legacy or existing systems is essential. Its molded case construction and included load-side lugs make it a practical, form-fit-functional replacement for compatible installations requiring a 100A, 3-pole configuration.

Designed to meet the demands of three-phase power distribution, the CA3100X helps safeguard conductors and equipment from overloads and short circuits. With its defined ampere rating and A.I.C. capacity, this breaker is intended to align with systems engineered for 240VAC environments. Whether maintaining facility infrastructure or replacing an existing CA frame breaker, the CA3100X delivers the ratings and configuration required for continuity and code-aligned operation.
