Electromechanical contactors are heavy-duty relays designed for switching high-power AC and DC loads — primarily three-phase motors, heaters, and power distribution circuits in industrial machinery, HVAC systems, and electrical panels. Our contactor inventory covers IEC and NEMA frame sizes with 3-pole and 4-pole configurations from Schneider Electric (TeSys D/LC1 series), Siemens (3RT/3TF series), ABB (AF/AX series), and Eaton (DILM series) — with coil voltages from 24V to 600V AC/DC, continuous current ratings from 9A to 800A, and AC-3 motor switching ratings up to 400kW.
Specific contactor configurations — particularly high-current (>100A) contactors for industrial motor control and contactors with specific coil voltages for legacy equipment — are frequently on allocation or discontinued. Welllinkchips stocks standard contactor types and can source obsolete contactor configurations for legacy industrial equipment maintenance.
