Multiquip 0601805840 Circuit Breaker KM-52 265V 50A

The Multiquip 0601805840 Circuit Breaker KM-52 265V 50A is a genuine OEM component designed for the DCA series ultra-silent diesel generator lineup, including DCA25SSI, DCA40SSI, DCA60SSI2, DCA125SSK, DCA150SSK2, DCA180SSK, DCA220SSK, DCA300SSK, DCA400SSK, DCA400SPK, DCA500SSK, DCA600SSK, DCA600SSV, and DCA800SSK models. Sourced directly from Multiquip, this is an exact-specification replacement rated at 265V and 50A, matching the original electrical protection requirements of your generator. Keeping a correct-spec circuit breaker installed is critical to protecting the generator's internal wiring and connected loads from overcurrent events.

Key Features

• Rated 265V / 50A — Matches the original overcurrent protection specification for DCA series generators, ensuring the breaker trips at the correct threshold to protect sensitive generator circuitry.
• Genuine OEM Part — Supplied by Multiquip as part number 0601805840, built to the same electrical tolerances as the component it replaces.
• Direct Drop-In Replacement — KM-52 form factor installs into the existing breaker position without modification to the panel or wiring harness.
• Broad DCA Series Coverage — Fits a wide range of Multiquip ultra-silent generators from the DCA25SSI through DCA800SSK, making it a practical stock item for fleets running multiple DCA units.
• Electrical Safety Compliance — A correctly rated circuit breaker is a critical safety component in any generator; using the specified 50A / 265V breaker ensures overcurrent protection operates as the machine was engineered to deliver.

A circuit breaker in a diesel generator acts as the primary overcurrent protection device between the generator's alternator output and the load distribution panel. When current draw exceeds the rated threshold — whether from a fault, a short circuit, or an overload condition — the breaker trips to interrupt the circuit and prevent damage to wiring, alternator windings, and connected equipment. A breaker that has worn contacts, fails to trip at the correct current, or has been incorrectly substituted with a different rating leaves the generator's electrical system exposed to potentially serious damage. Replacing a faulty or tripped-but-damaged breaker with the correct Multiquip 0601805840 restores proper overcurrent protection and keeps the generator operating within its designed safety parameters.
