267194 - Miller 30A 250V Manual Reset Circuit Breaker 2-Pole

Genuine Miller 267194 Replacement Circuit Breaker

Restore the functionality and safety of your Miller welding power source with the Miller 267194 Supplementary Protector. This component serves as the first line of defense against electrical overloads, protecting sensitive internal electronics and wiring from excessive current. Rated for 30 Amps and 250 Volts, this 2-pole breaker is designed to interrupt power instantly when current levels exceed safe operating limits, preventing heat damage and potential fire hazards within the machine.

The manual reset feature of this protector is a key operational benefit. Unlike automatic reset breakers that might cycle on and off repeatedly during a fault—potentially causing further damage—this manual unit stays tripped until an operator intervenes. This forces a pause in operations, prompting the user to investigate the cause of the overload (such as a shorted cable or duty cycle exceedance) before re-energizing the system. The tactile reset button provides immediate feedback on the circuit status.

Technical Specifications and Fitment

This supplementary protector is engineered for specific Miller equipment. Its 2-pole architecture is essential for circuits requiring the disconnection of two lines, common in higher voltage single-phase applications. The robust casing is designed to fit securely into the machine's front panel or internal chassis, ensuring a solid mechanical mount that resists loosening over time. Electrical connections are standard for this class of component, facilitating a straightforward swap-out process for qualified repair technicians.

When replacing a circuit breaker, accuracy is paramount. The Miller 267194 is not a generic "one-size-fits-all" part; it is calibrated to the thermal and magnetic trip characteristics required by Miller engineering. Using this exact part number ensures that your machine retains its UL/CSA listings and operates within its designed safety margins. Do not compromise on electrical safety—choose the Miller 267194 for a direct, reliable replacement that gets your welder back in production with confidence.
