COMMON QUESTIONS
Frequently Asked Questions
Definite purpose contactors are designed for specific applications like HVAC, refrigeration, and resistive heating, offering a compact, cost-effective solution compared to general-purpose contactors.
We offer 20-30 FLA and 40 FLA series definite purpose contactors in 1-pole, 2-pole, and 3-pole configurations for HVAC, refrigeration, and electric heating applications.
FLA (Full Load Amps) is the current rating for the contactor under specific application conditions. 20-30 FLA models handle 20-30A, while 40 FLA models handle 40A at rated voltage.
Available with 24V, 120V, 208/240V, and 480V AC coils at 50/60Hz, covering standard control voltages used in HVAC and commercial equipment.
Yes, they are rated for both inductive (motor) and resistive (heater) loads per their definite purpose designation, with Locked Rotor Amps (LRA) ratings specified.
They carry UL and CSA certifications, compliant with UL 508 and CSA C22.2 standards for North American HVAC equipment.
