See Back for Installation Instructions
The Model A50 Current Sensing Relay
measures electrical current rather than
voltage. This type of relay is more reliable
and less expensive than using sail switches,
pressure switches or other types of relays.
The relay is easily installed around the
common lead of the blower motor and
inserted into the circuitry. (See wiring
diagrams on back.)
