The Honda 31430-ZB5-830 Circuit Breaker (30A) is a genuine OEM replacement designed for the EV4010, EV6010, and EVD4010 RV generators. As a factory-sourced component, this circuit breaker matches Honda's original specifications exactly, ensuring a direct swap with no guesswork on rating or fitment. Verify your generator's model and serial number against the fitment table before ordering to confirm this is the correct 30A unit for your machine.
Key Features
- Genuine OEM Protection Rating — sourced directly from Honda, this circuit breaker carries the correct 30A interruption rating your RV generator's electrical system requires, avoiding the risk of an undersized or oversized replacement tripping too early or failing to protect the circuit.
- Direct OEM Replacement — designed as an exact fit for the EV4010, EV6010, and EVD4010 RV generators, this part drops into position without modification.
- Serial-Range Awareness — Honda revises parts at production serial breaks; confirm your generator's serial number against the fitment table to ensure part number 31430-ZB5-830 is the correct supersession for your unit.
- Restored Circuit Protection — a failed or tripped-and-damaged breaker leaves the generator's output circuits unprotected; replacing it with this genuine part restores normal overload and short-circuit protection to your RV generator.
A circuit breaker is an automatic switching device that protects an electrical circuit from damage caused by excess current — whether from an overload or a short circuit. In an RV generator like the EV4010, EV6010, or EVD4010, the circuit breaker monitors the output current and trips open the circuit the moment current exceeds its rated threshold, cutting power before wiring or connected equipment can be harmed. Once the fault is cleared, the breaker can be reset, but a breaker that no longer trips reliably — or one that fails to reset — must be replaced promptly to maintain safe, functional power output from the generator.
