Supports a wide voltage range of 115V-220V

this switch opens due to insufficient draft in the heat exchanger

whereas you should never replace a 440V unit with a lower-rated 370V model

This 440V HVAC capacitor is a versatile service part that can safely replace 370V equivalents

it can function in any 24V application requiring an SPDT relay
