The Cutler Hammer-Eaton C25DNF340B Contactor is an electrical switch is intended for used in HVAC systems, to control high-power AC loads in air conditioning systems. Approved for 40 Amps and designed to work at 208 – 240 VAC, this 3-pole contactor controls the power input to items such as the compressor and the condenser fan motor. When the thermostat feels that it's hot, it triggers the contactor to close and make electricity flow. This effective functioning is better for regulating the performance of HVAC systems as well as for respecting energy efficiency by avoiding false energy costs in idle periods. This is especially useful in regulating indoor temperatures and improving comfort while at the same time extending the useful life of HVAC systems.
