The Honda 38220-ZS4-V70 is a genuine OEM Circuit Protector (21A) designed for the EX5500 generator. Sourced directly from Honda, this component matches the original specification and drops straight into place without modification. Confirm part number 38220-ZS4-V70 against your unit's serial number before ordering to ensure you have the correct rating for your application.
Key Features
- Genuine OEM Protection Rating — the 21A trip rating matches Honda's original design exactly, ensuring the generator's electrical output circuits are protected at the correct threshold, not approximated by a generic substitute.
- Direct Replacement — built to the same form and connection standard as the original, this Circuit Protector installs into the EX5500 without rework or adaptation.
- EX5500 Generator Fitment — confirmed fit for the EX5500 generator; check your serial number against the fitment table to verify this is the correct variant for your production run.
- Restored Electrical Reliability — a failed or weak circuit protector can leave output circuits unprotected or trip nuisance faults under normal load; replacing it with this genuine part restores correct overcurrent protection to the generator.
A circuit protector is a resettable overcurrent device that guards the generator's AC output circuits against excessive current draw. When a connected load draws more current than the rated threshold, the protector trips and interrupts the circuit, preventing damage to the generator's wiring and alternator. Unlike a one-time fuse, a circuit protector can be reset once the overload condition is cleared, but a unit that trips repeatedly under normal loads or that no longer resets reliably has reached the end of its service life and should be replaced to keep the generator's output circuits properly protected.
