Used Contactors

Verify coil voltage, main contact current rating, AC/DC type, number of poles and auxiliaries, part numbers and compatibility with your starter/control circuits, visible contact wear or pitting, and any test records.

De-energize and isolate coils, cap terminals, secure moving parts, pack with anti-static and moisture protection, cushion to prevent shock, and use a tracked carrier or pallet with clear labeling for heavy or bulky assemblies.

Inspect contacts for pitting, measure coil resistance and contact resistance, verify mechanical operation and auxiliary contacts, tighten terminals, clean corrosion, and replace heavily worn or welded contacts. Test under load after service.
