Emerson Climate-White Rodgers 90-170 3-Pole Contactor 40 AMP 24V

The Emerson Climate-White Rodgers 90-170 3-Pole Contactor is a definite-purpose electrical switching part to control high-voltage components through a low-voltage control signal. It operates with a 24V coil and uses three poles to switch compressors, condenser fans, or other load circuits during heating and cooling operation. Its electromagnetic coil operates internal contacts that manage high-current components such as compressors, fan motors, and auxiliary loads within HVAC systems. Its stable switching action improves electrical coordination and provides safe system efficiency during frequent start-stop cycles.
