CA2100Y - 100Amp Circuit Breaker

CA2100Y - 100 Amp Circuit Breaker

The CA2100Y circuit breaker is a 2-pole, 100 amp molded case circuit breaker designed to provide dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CA frame platform and rated for 10kA interrupting capacity, this breaker is well suited for protecting branch circuits, subpanels, and light commercial distribution equipment. With a non-interchangeable trip unit calibrated for operation at 40°C, the CA2100Y is engineered for consistent performance under standard operating conditions. Line-side lugs are included, helping ensure proper conductor termination and secure installation. For facilities maintaining or servicing existing electrical infrastructure, this breaker offers the correct form, fit, and function required for compatible CA frame applications.

Designed with durability in mind, the CA2100Y molded case circuit breaker is constructed to withstand the demands of everyday electrical use. Its compact profile and solid construction make it a practical solution for maintaining safe and code-compliant power distribution systems in commercial, industrial, and institutional environments.
