Multiquip 0605503062 Fuel Leak Detected Switch

The Multiquip 0605503062 Fuel Leak Detected Switch is a genuine OEM component designed for DCA series Ultra-Silent and Super-Silent diesel generators. This switch is a direct OEM replacement sourced to exact Multiquip specifications, ensuring correct installation and reliable operation across the wide range of DCA generator models it covers. Compatible units include the DCA45SSIU4F, DCA70SSIU4F, DCA125SSIU4F, DCA150SSJU4F, DCA180SSJU4F, DCA220SSJU4F, DCA300SSJU4F, DCA70USI, DCA85USJ, DCA125USI, DCA150USJ, DCA36SPXU4F, and related variants. Keeping this switch in proper working order is essential for generator safety and uninterrupted operation on any worksite.

Key Features

• Genuine OEM Sensing Accuracy — Built to the exact electrical and mechanical specification Multiquip engineered into the DCA generator line, ensuring the switch triggers correctly at the right threshold.
• Drop-In Replacement — Matches the original connector type, mounting configuration, and wiring interface for a clean, direct swap with no adaptation needed.
• Broad DCA Series Coverage — Fits a wide range of Ultra-Silent and Super-Silent DCA models from the DCA36SPXU4F through the DCA300SSJU4F, including Isuzu and John Deere powered variants.
• Critical Fuel System Safety Component — This switch is part of the generator's fuel leak detection circuit; a failed or missing switch can prevent the system from detecting a fuel leak, creating a serious fire and safety hazard.
• Supports Generator Shutdown Protection — When functioning correctly, this switch enables the generator's protection system to respond to a fuel leak condition and initiate a controlled shutdown before damage or injury occurs.

The Fuel Leak Detected Switch is a safety-critical sensor in the generator's fuel leak detection circuit. Its job is to monitor for the presence of fuel outside the normal fuel system boundary and signal the generator's control board when a leak condition is detected, triggering a protective shutdown. When this switch fails, becomes corroded, or is stuck in either position, the generator may shut down unexpectedly during normal operation or — more dangerously — may fail to shut down when an actual fuel leak occurs. Replacing a worn or faulty switch with a genuine Multiquip OEM part ensures the detection circuit responds exactly as designed.
