The Honda 38240-ZC6-E31 Circuit Protector (20A) is a genuine OEM component designed for Honda EB, EG, EM, ES, EU, EW, and EX series generators, including the EB11000, EB3500, EB5000, EB6500, EG3500, EG5000, EM3500, EM5000, EM6000, ES6500, EU3000, EW171, EX4500, and EX5500. As a direct Honda OEM replacement, this circuit protector carries the exact 20A rating and trip characteristics your generator's electrical panel calls for. Verify your generator's serial number against the fitment table to confirm this is the correct part for your unit before ordering.
Key Features
- Correct Amperage Rating — rated at exactly 20A to match the original protection spec on covered Honda generator models, ensuring the output circuit trips at the right threshold and not before or after
- Genuine Honda OEM Component — sourced directly from Honda, this part meets the same electrical and mechanical standards as the unit it replaces, with no calibration or adaptation needed
- Broad Generator Compatibility — fits a wide range of Honda conventional generators, inverter generators, and welder generators, including the EB11000, EB5000, EG5000, EM6000, EU3000, EW171, EX5500, and more
- Serial Number Verification Recommended — Honda updates electrical components at production serial breaks; check your generator's serial number against the fitment table to confirm this 20A protector is correct for your specific unit
A circuit protector is a resettable overcurrent protection device built into the generator's output panel. When a connected load draws more current than the rated threshold — 20A in this case — the protector trips and interrupts power to that circuit, preventing damage to both the generator's wiring and the connected equipment. Unlike a fuse, a circuit protector can be reset once the overload is cleared. A protector that fails to trip leaves downstream wiring and equipment exposed to damaging current; one that nuisance-trips under normal load causes unnecessary shutdowns. Either condition points to a worn or faulty protector that needs replacement to restore dependable power distribution from the generator.
