5-22 Field-loss Relays IC2820D300 WHERE TO USE Use to protect dc shunt or compound- pick-up to be set below minimum field cur- wound motors against loss of field excita- rent. Relay will not protect against over- tion. The coil of the relay is connected in speed due to weak field unless the field series with the motor field. When excitation current decreases below the relay dropout is lost, the relay drops out and opens the setting. motor line contactor. HOW TO ORDER Select relay so that continuous rating will not be exceeded by the rated field current Order by complete IC number. EXAM- and the relay calibration range permits PLE: IC2820D300A2.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
