The Wacker Neuson Circuit Breaker is a genuine OEM component designed for the GPi4300 and GPSi4300 inverter generators. Sourced directly from Wacker Neuson, this is the same part installed at the factory — ensuring correct electrical ratings, terminal fit, and trip characteristics for these machines. It installs as a direct replacement with no adapting or modifying the existing circuit panel. If your inverter generator has lost output protection or a breaker has tripped and will not reset, this is the correct service part to restore proper operation.
Key Features
- Correct Trip Rating for Inverter Generator Circuits — Genuine OEM spec means this breaker is calibrated to the exact current threshold Wacker Neuson engineered for the GPi4300 and GPSi4300 output circuits — not an approximation.
- Direct Terminal Fit — Designed to seat and connect exactly as the original, with matching terminal configuration for the existing panel mount — swap out and reconnect without reworking the wiring.
- Fits GPi4300 and GPSi4300 Inverter Generators — Confirmed fitment for both the standard GPi4300 and the GPSi4300 models, covering the core inverter generator series in this Wacker Neuson lineup.
- Protects Sensitive Inverter Electronics — A properly functioning circuit breaker is the first line of defense for the inverter module and connected loads. A failed or weak breaker leaves downstream components exposed to damaging overcurrent events.
- Electrical Safety Compliance — As a protective device in the generator's electrical system, using the correct OEM-rated breaker ensures the machine operates within its designed safety parameters — critical for both operator protection and connected equipment.
A circuit breaker in an inverter generator acts as the automatic safety switch between the generator's output and the load being powered. When current draw exceeds the rated limit — whether from an overload, a short circuit, or a fault in connected equipment — the breaker trips and cuts power before damage can occur. Over time, breakers can weaken from repeated trips or simply fail to reset, leaving the generator unable to deliver power even when the underlying issue has been cleared. Replacing a faulty breaker with part number 5000183873 restores that critical protection layer and gets the machine back to full, safe output.
