Multiquip 0601870451 GFCI Breaker 40A 2P

The Multiquip 0601870451 is a genuine OEM GFCI Breaker 40A 2P designed for GA-9.7HEA gasoline-powered generators and DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welder units. As a direct OEM replacement, 0601870451 is sourced and validated by Multiquip to match the original electrical specifications of the output protection circuit on these machines. Buying genuine OEM means you receive a component built to the exact amperage rating and pole configuration required — no guesswork on electrical compatibility. If you are servicing a GA-9.7HEA or DLW300ES series unit, this is the correct breaker for the application.

Key Features

• Correct 40A, 2-Pole Rating — Matched to the output circuit protection requirements of the GA-9.7HEA and DLW300ES series, ensuring the breaker trips at the right threshold — not before, not after.
• Ground Fault Circuit Interrupter Protection — Provides GFCI-rated protection at the power output, interrupting current in the event of a ground fault to protect connected equipment and operators.
• Genuine OEM Component — Supplied by Multiquip as a direct factory replacement, validated to meet original electrical design specifications for these generator and welder platforms.
• Direct-Fit Replacement — Designed to install into the existing breaker position on covered models without modification to wiring or panel mounting.
• Confirmed Fitment for GA-9.7HEA and DLW300ES Series — Verified compatibility across the DLW300ES, DLW300ESA, and DLW300ESA1 diesel light welders and the GA-9.7HEA gasoline-powered generator.
• Electrical Safety Compliance — A correctly rated GFCI breaker is a critical safety component on generator and welder output circuits; using an incorrect or worn breaker risks nuisance tripping or, more seriously, failure to protect against ground faults.

A GFCI breaker combines the overcurrent protection of a standard circuit breaker with ground fault detection, continuously monitoring the current flowing through the circuit and tripping immediately if it detects a leakage path to ground. On generator and welder platforms like the DLW300ES series and GA-9.7HEA, this breaker sits at the power output panel and protects both the machine and any connected tools or equipment. When a GFCI breaker fails or becomes worn, it may trip unexpectedly under normal load, refuse to reset, or — most critically — fail to trip when a genuine ground fault occurs, creating a serious shock hazard for the operator.
