CAH2100 - 100Amp Circuit Breaker

CAH2100 - 100 Amp Circuit Breaker

The CAH2100 molded case circuit breaker is a 2-pole, 100 amp breaker designed for dependable overcurrent protection in 120/240VAC electrical distribution systems. Built on the CAH frame, this breaker features a non-interchangeable trip unit calibrated for consistent operation at 40°C. With a 22kA A.I.C. rating, the CAH2100 is well-suited for protecting branch circuits and feeder applications where reliable interruption capacity is required. Line and load-side lugs are included, supporting straightforward installation and secure conductor termination. Designed to meet the form, fit, and function requirements of existing CAH frame installations, this breaker is an effective replacement solution for maintaining the integrity of legacy electrical systems. Constructed as a molded case circuit breaker (MCCB), the CAH2100 is built for long-term durability under normal operating conditions. Its compact footprint—approximately 6.5 inches in height and a ship weight of 2.75 lbs—allows it to integrate seamlessly into compatible panelboards and distribution equipment originally designed for the CAH frame type.
