What is a lighting contactor?
Lighting contactors are relay switches that control the flow of electricity through a circuit powering the lighting in a given area. They exist remotely and control circuits with higher voltages which can be dangerous to the operator, if controlled directly.
How long will a contactor last?
– 10 years
How long do AC contactors last? With the right maintenance, a good contactor will typically last between 5 – 10 years. During a maintenance service, the technician will check the contactor to make sure it is working properly.
What is difference between general purpose and definite purpose contactor?
Unlike General purpose contactors, which are rated typically based on HorsePower (HP) of the motor, Definite Purpose contactors are rated on Motor Full Load Amps (FLA). DP contactors often have limitations on the maximum Locked Rotor Amps (LRA) it can handle.
How can you tell if a contactor is bad?
A bad AC contactor can be identified by physical signs of deterioration, also known as pitting. Pitting occurs when the contactor has encountered extreme voltage and heat. A pitted contactor tends to stick, causing a continuous flow of electricity to the unit.
How long should a contactor last?
Why is it called definite purpose contactor?
A common contactor in the HVAC industry is the Definite Purpose Contactor. As the name suggests, it was designed for a specific or “definite” purpose — HVAC applications (Heating, Ventilation, Air Conditioning and Refrigeration).
