Wacker Neuson 5000163870 Circuit Breaker W/Switch 2P 27A

The Wacker Neuson Circuit Breaker W/Switch 2P 27A is a genuine OEM component designed for the GP6600A and GPS6600A series premium portable generators. As a direct OEM replacement, this two-pole 27-amp breaker with integrated switch is sourced from Wacker Neuson and built to the exact specification required by the GP6600A and GPS6600A platforms, including the wheel kit variant. Confirm your generator's model number against the fitment list before ordering to ensure a correct, hassle-free installation.

Key Features

• Genuine OEM Electrical Compliance — Rated at the correct 2-pole, 27-amp specification to match the generator's designed circuit protection requirements exactly.
• Integrated Switch Function — Combines circuit protection and manual switching in a single unit, replacing the complete breaker-switch assembly in one straightforward swap.
• Verified Generator Fitment — Confirmed for the GP6600A (standard and wheel kit) and GPS6600A premium portable generator series.
• Protects Critical Generator Output Circuits — A correctly rated breaker prevents overcurrent damage to the generator's wiring and connected equipment; an undersized or failed breaker puts both the machine and the load at risk.
• Electrical Safety Critical — Circuit breakers are a core safety component in any generator system; using the correct OEM-rated part ensures the protection circuit trips at the engineered threshold, not before or after.

A circuit breaker with switch in a portable generator serves two related roles: it interrupts current flow automatically when a circuit is overloaded or a fault occurs, and it allows the operator to manually disconnect the output circuit when needed. In the GP6600A and GPS6600A generators, this 2-pole 27-amp unit protects downstream wiring and connected tools from excessive current draw. When this breaker fails — whether through nuisance tripping, failure to trip, or a faulty switch mechanism — the generator may either cut power unexpectedly or, more dangerously, fail to protect against an overcurrent condition. Replacing a worn or damaged breaker with the correct Wacker Neuson 5000163870 restores proper circuit protection and manual control.
