Generac Part 5621 Auxiliary Transfer Switch Contact Kit
The Generac Model 5621 Auxiliary Transfer Switch Contact Kit is a small but highly functional electrical accessory used by professional installers within a Generac Automatic Transfer Switch (ATS) to implement basic load management for a single, high-amperage appliance. The kit consists of a set of dry (non-powered) auxiliary contacts and mounting hardware. Its primary job is to interrupt the low-voltage control signal for a specific appliance when the system is running on generator power.
Features
Single Load Lockout:
- The primary function is to lock out a single, high-amperage appliance (like electric heat, an electric furnace, or a second large air conditioner) when the home is running on generator power.
Overload Prevention:
- By preventing a high-demand appliance from receiving power, the kit ensures the generator stays within its safe operating limits, preventing shutdowns and maximizing power availability for critical circuits.
Low-Voltage Control:
- It operates by interrupting the low-voltage control signal (typically the thermostat or control wiring) for the appliance, rather than switching the main power wires.
Cost-Effective Management:
- It provides a basic, cost-effective form of load management, allowing a homeowner to use a smaller, less expensive generator while still providing coverage for their most essential needs.
Easy ATS Integration:
- The kit is designed to be installed directly inside the Generac ATS panel, integrating seamlessly with the switch's functionality.
Compatibility:
- Works with most Generac, Guardian Series, and other Generac-branded single-phase Automatic Transfer Switches.
