Recommended Motor Contactor Maintenance & Inspection
Recommended Motor Contactor Maintenance & Inspection
(OP)
Does anyone have a reference for the recommended interval of maintenance and inspection of motor contactors? This would be a recommended practice or interval for inspecting the contacts for pitting and wear, etc.
thanks

RE: Recommended Motor Contactor Maintenance & Inspection
Also, it will be different for NEMA versus IEC contactors.
I'm sure manufacturers have specific recommendations.
FWIW , NETA recommendations for both low voltage and medium-voltage contactors:
Visual inspection - every two months
Visual & Mechanical - every 12 months
Visual, Mech, & Electrical - every 24 months.
NETA (www.netaworld.org) has detailed specifications for maintenance testing that you could use as at least a starting point.
