CA3100W - 100Amp Circuit Breaker

CA3100W - 100 Amp Circuit Breaker

The CA3100W molded case circuit breaker is a 3-pole, 100-amp unit designed for dependable circuit protection in commercial and industrial distribution systems operating at up to 240VAC. Built on the CA frame platform, this breaker features a non-interchangeable trip unit calibrated for 40°C applications, helping maintain consistent thermal-magnetic protection under standard operating conditions. With a 10kA interrupting capacity at 240VAC, the CA3100W is engineered to provide reliable overcurrent and short-circuit protection in legacy electrical panels and switchboards where CA frame breakers are specified. This model ships without lugs installed, allowing for field-configured terminations based on application requirements. Designed for proper form, fit, and function, the CA3100W is well-suited as a direct replacement in existing systems requiring the same electrical ratings and frame type.

Key Features and Benefits

• 100 Amp Continuous Rating: Supports branch and feeder circuit protection in commercial and light industrial environments.
• 3-Pole Configuration: Ideal for three-phase electrical systems requiring consistent overcurrent protection across all phases.
• 10kA Interrupting Capacity at 240VAC: Rated to safely interrupt fault currents up to 10,000 amperes at 240 volts AC.
• CA Frame Type: Designed for compatibility with equipment utilizing CA frame molded case circuit breakers.
