Description
Overview:
This Generator Changeover Switch 110V/240V is a non-genuine replacement part designed for small air-cooled diesel generators around 2.1 kW. Built from durable materials for everyday use, it selects and switches the generator's output between 110 V and 240 V on compatible models, helping you match the supply to the tools or site equipment in use. The 6‐terminal layout supports common generator winding configurations, providing dependable performance in home, site, and light industrial settings. Marked with MPN 879 500, it is suitable for popular units such as the 3400HM4S and 5000HMS. Use it to restore reliable voltage selection and smooth changeover on machines where the original switch has worn, failed, or become intermittent.
Key Features:
- Dual-voltage operation: supports 110 V and 240 V selection for flexible use on UK sites and at home
- 6-terminal design for straightforward integration with typical dual-winding generator alternators
- Durable construction for long service life under regular vibration and temperature changes
- Consistent, positive switching helps reduce arcing and nuisance trips during changeover
- Non-genuine, high-quality replacement that offers practical performance and value
- Suitable for air-cooled diesel generators around 2.1 kW, restoring reliable output selection
- Compatible with several popular models to simplify sourcing and maintenance
- Compact form factor to aid like-for-like replacement when matching the existing mounting and wiring
- Helps maintain uptime during power needs on site, in workshops, and for backup use
- Identified by MPN 879 500 for easy cross-reference against parts lists
Typical Applications:
Used on portable and stationary diesel generators to switch the output between 110 V (for site tools via transformers) and 240 V (for single-phase equipment). Suitable for maintenance replacements, refurbishments, or fault rectification where the original changeover switch is worn or damaged. Helps keep domestic, commercial, and light industrial operations running safely and efficiently during routine use or outages.
