Multiquip Y0601808837 Circuit Breaker Motorized 800A - OEM Replacement Part

This motorized 800-amp 3-pole main circuit breaker provides primary overcurrent protection for the generator's output system, automatically disconnecting power during overload or fault conditions to protect both the generator and connected equipment. Installed in the control box behind the control panel alongside the automatic voltage regulator, rectifier, DEIF controller (AGC-4), and overcurrent relay, this circuit breaker is a critical safety component in the electrical distribution system.

The 800-amp rating is designed to handle the substantial output capacity of super silent generator units, protecting the output terminal panel connections including the UVWO terminals, CS-6369 twist-lock receptacles, and GFCI receptacles. The motorized operation allows for remote control and integration with the generator's automated control systems. When this breaker fails or trips repeatedly, symptoms may include inability to restore power, loss of output despite normal engine operation, or failure of the DEIF controller to properly manage load distribution across the 3-phase 240/139-volt or single-phase configurations.
