Mars 61683 480V Coil 3 Pole 20-40A Contactor Coil

Product Description

The MARS 61683 is a 480-volt replacement contactor coil designed for 3-pole contactors rated from 20 to 40 amps. MARS, short for Motors and Armatures, has long been a trusted supplier of electrical components for HVAC and refrigeration professionals. This coil is a critical part of any contactor assembly. When energized, the coil generates a magnetic field that pulls in the contactor armature, closing the power contacts and allowing current to flow to the load. When de-energized, the contacts open and the circuit is interrupted. This switching action is fundamental to how HVAC equipment such as air conditioners, heat pumps, rooftop units, and refrigeration systems cycle their compressors and fan motors on and off. A failed or burned contactor coil is one of the most common causes of no-cooling or no-heating calls. The MARS 61683 allows technicians to replace just the coil rather than the entire contactor assembly, saving time and reducing parts cost on the job. It is rated for 480 volts, which is standard in commercial and light industrial HVAC applications. The 3-pole configuration means three sets of contacts are controlled simultaneously, as required for three-phase motor loads. The 20 to 40 amp range covers a wide variety of commercial compressors and motor contactors found in the field. HVAC technicians, refrigeration mechanics, and electrical contractors working on commercial equipment will find this coil a reliable replacement option. Keeping this part stocked in a service van helps reduce equipment downtime and speeds up repair calls on commercial rooftop units, chillers, and other 480-volt three-phase systems.
