How do you check the Series B 8502SG control coil resistance?
Issue:
How to measure 8502 Size 5 Coil resistance?
Product Line:
NEMA and Definite Purpose Contactors and Starters
Environment:
Type S Contactors and Starters
Cause:
The coil cannot be measured directly with an ohmmeter
Resolution:
The resistance of this coil cannot be measured with an ohmmeter. A properly functioning coil, when isolated from its control circuit draws between 0.3 ma and 10 ma (depending upon its voltage) when connected to a 9 volt battery
This also applies to all 8536SG, 8538SG, 8539SG, 8606SG, 8630SG, 8640SG, 8702SG, 8736SG, 8738SG, 8739SG, 8810SG, 8903SX, 8910SYD368, and 8940 Size 5 except ``NP`` devices. For enclosed devices, the series information is based on device and not enclosure nameplate
