Control fans blowers motors up to 1 1 2hp tools and other electrical devices within ratings. Blower motors are a common component in a home commercial and automotive hvac systems.

The relay contains a low voltage coil and a high voltage switch sometimes called contact points when the thermostat switches on a low voltage signal energizes the appropriate relay.
