ClimateMaster 13B0003N02 3-Pole Contactor 40A 24V Coil

The ClimateMaster 13B0003N02 3-pole contactor is an electrically controlled switch used in HVAC systems. This particular model deals with 40 amps and uses a 24-volt coil to activate the switch. These contractors are useful when it comes to managing high power loads in HVAC equipment including compressors, fans, and electric heaters. When the thermostat demands heat or cool air, a small electric current flows through the 24V coil, which attracts the contactor’s poles, closing the circuit and powering other large HVAC parts. This enables the on/off control of these high power loads to be accomplished safely and efficiently.
