Circuit breaker for P&H 2100BLE

The circuit breaker functions as an electrical safety device within the control cabinets of heavy mining equipment. It monitors the current flow and automatically interrupts the circuit when it detects an electrical anomaly, such as an overload or a short circuit, preventing potential damage to the machine's internal electrical systems. This component is specifically rated for 100A service.

This part is compatible with P&H shovel models 2100BLE and 2800. It is also identified by the Westinghouse part number JD3250F-JT125-A1X1-SNT2 and is manufactured by Harnischfeger Corp. The component is installed within the upper machinery control cabinet to manage power distribution to various electrical subsystems, including motors and control modules.

In heavy machinery, circuit breakers serve as the primary defense against electrical faults. By isolating affected circuits during a power surge or failure, they protect sensitive wiring and expensive electrical components from thermal damage. Regular inspection of these devices ensures that the electrical distribution system remains stable and that the machine maintains its operational safety standards during demanding work cycles.
