CA3125 - 125Amp Circuit Breaker Description

CA3125 - 125 Amp Circuit Breaker

The CA3125 molded case circuit breaker is a 125 amp, 3-pole breaker built for use in commercial and industrial electrical distribution systems operating at 240VAC. Designed on the CA frame platform, it provides thermal-magnetic overcurrent protection with a 10kA interrupting rating. This unit features a non-interchangeable trip and includes both line and load-side lugs for straightforward installation. Rated for operation in 40°C environments, the CA3125 is built to last and serves as a direct form, fit, and functional replacement for compatible CA-frame equipment.

When maintaining existing panelboards or replacing a failed breaker, matching the correct frame type, amperage, and interrupting capacity is critical. The CA3125 is configured specifically for applications that require a 125A, 3-pole breaker within the CA series.
