Lennox 48G58 3-Pole Contactor 25 AMP 24V

The Lennox 48G58 Contactor is a device in the HVAC category which is an electromagnetic switch. It works like a high current switch, regulating high current flow up to 25A between a power supply and loads such as compressor, heater or fan. When the low voltage control circuit is energized, normally between 24 volts, When the control circuit is off, the magnet pulls out and thus no more current is allowed to pass through the circuit. This contactor is a small, that is, 3.5 x 4.1 x 3.1 inches in dimension, Thus, contactors bear the high current during operation and reduce the wear of other electrical components especially during starting.
