JDB3125 - 125Amp Circuit Breaker Description
JDB3125 - 125Amp Circuit Breaker
A replacement breaker has several details that need to align, and the JDB3125 provides a specific checklist to check. This Eaton Series C molded-case circuit breaker is rated at 125 amps and has three poles, a J frame, JDB breaker type, and T186 trip type. The JDB3125 is built to last, while its clearly defined ratings and physical characteristics make it a practical form, fit, and functional replacement when your existing or legacy equipment specifically calls for this configuration.
Key Features and Benefits

Where It Works Best
The JDB3125 is best considered for compatible existing and legacy electrical equipment that specifically requires a 125A, three-pole JDB breaker with a J frame and T186 trip type. The included aluminum line and load terminals are another detail to compare with the existing installation, rather than assuming compatibility based on amperage alone.
