The Wacker Neuson OW-497 is a genuine OEM Lockout Switch designed for the full range of Wacker Neuson G-series portable generators, including G25, G50, G70, G100, G120, G130, G150, G180, and G240 models across standard, cold weather, extended run, and custom configurations. As a factory-sourced component, the OW-497 delivers the exact electrical specifications and mechanical fit required to maintain safe, code-compliant generator operation. This Lockout Switch covers an extensive range of G-series variants — including Tier 4 Final, Tier 4i, Tier 3, and 600V switchable configurations — making it the go-to replacement for fleet operators and service technicians working across multiple generator sizes. Confirm your model number before ordering to ensure correct fitment within this broad G-series application range.

Key Features

  • Genuine OEM Electrical Specification — Sourced directly from Wacker Neuson, this Lockout Switch meets the exact switching capacity, contact rating, and actuation force required for G-series generator control circuits — no guesswork on electrical compatibility.
  • Drop-In Replacement — Engineered to match the original mounting footprint and wiring interface of the factory-installed unit, allowing straightforward swap-out during scheduled maintenance or field service.
  • Broad G-Series Fitment — Compatible with G25, G50, G60, G70, G95, G100, G110, G120, G130, G150, G180, G230, G240, and G40 generator models across standard, cold weather, extended run, skid-mounted, mobile, and 600V switchable variants.
  • Critical Safety Function — A properly functioning lockout switch is essential to isolating generator output and preventing inadvertent energization during service, panel connections, or load transfer — protecting both equipment and personnel.
  • Supports Consistent Fleet Uptime — With coverage across dozens of G-series configurations, a single OW-497 part number simplifies parts inventory management for rental fleets and service contractors running mixed generator lineups.

A lockout switch on a portable generator is an electrical safety device that controls or interrupts output power, preventing the generator from being energized under specific conditions — such as during servicing, load connection, or transfer switching. It acts as a deliberate barrier between the generator's electrical output and downstream equipment, ensuring operators and technicians cannot inadvertently make contact with live circuits. When a lockout switch wears out, sticks, or fails to actuate cleanly, it can compromise both operational safety and compliance with lockout/tagout (LOTO) procedures, making timely replacement essential on any job site where the generator is regularly serviced or connected to permanent electrical infrastructure.
