Designed for HVAC/R Compressor Duty – Definite purpose contactors are specifically engineered for the high-inrush currents of compressor motors. The contact structure and silver metal oxide contacts handle locked-rotor amps (LRA) of 5–8× full-load amps without excessive contact erosion, ensuring reliable long-term operation in refrigeration and air conditioning systems.
Wide Pole & Current Range – Available in 1-pole, 1.5-pole, 2-pole and 3-pole configurations, with current ratings from 20A to 90A. This covers single-phase compressors, three-phase compressors, and condenser fan motor control in one product family.
Multiple Coil Voltage Options – Coil voltages from 24VAC to 600VAC support North American (24V, 120V, 208–240V, 277V, 480V) and international (220–240V, 380–415V) control circuits, reducing inventory complexity for distributors serving multiple markets.
Silver Metal Oxide Contacts – Contacts are made of silver metal oxide composition, providing high electrical endurance and resistance to welding under inductive load switching. This extends contactor life in high-cycle HVAC applications.
Class F Coil Insulation – Coil is insulated to Class F (155°C), suitable for high ambient temperature environments and continuous-duty compressor operation.
Dust-Resistant Encapsulated Design – Fully encapsulated or dust-resistant body prevents contaminants from entering the magnet structure, reducing noise and extending mechanical life in dusty or humid environments.
Universal Mounting Plate – Industry standard mounting plate allows drop-in replacement for major brands including Eaton, Siemens, ABB, Schneider, and others.
OEM & ODM Support – Custom logo, coil voltage, terminal type, and packaging available. Can produce according to customer specifications.
Export Packaging – Seaworthy carton and pallet packaging, suitable for long-distance ocean shipping.
