100 Amp Relay - By ExtremeAire
Continuous Duty Relay: The relay acts as a giant on/off switch that controls the high amperage to the compressor. The relay is controlled by the toggle switch and for systems that include an air tank, a pressure switch is on the same circuit (see wiring diagram). Only continuous duty relays of the correct amperage capability can be used, not doing so will void your compressors warranty. The relay uses less than 5 amps to energize and can be powered using 14-16 gauge wire for the switching post in most applications. Every compressor installation must utilize a continuous duty relay, failure to do so will void your warranty.
