Description
Carrier P283-0340 is a 2 pole fan relay with 24V coil applied in HVAC equipment. It is an electromagnetic relay that operates when a 24V electrical signal is used to switch on and off two different circuits. It works like a switch that is operated by a small current, but it can deal with greater voltages in the different circuits. Fan relays are an essential part of HVAC systems because they effectively control many fans such as exhaust fans, condenser fans, and others. One relay gives isolated control of two different circuits and make the wiring and the number of components less.
