Issue:
Adding an auxiliary alarm contact on the overload relay of an NEMA starter
Product Line:
NEMA Contactors and Starters
Environment:
NEMA Accessories
Cause:
Alarm contact need for overload relay
Resolution:
For isolated normally open on melting alloy (standard) type use Form Y342. For isolated normally closed on melting alloy type use Form Y344.
For Bimetallic Forms (B, B1 & B2), non-isolated normally open alarm contact is provided as standard. Isolated or normally closed is not available.
For isolated normally open on Solid State (Forms H30) type, change the "0" to "1". For example Form H30 becomes H31. This contact is field convertible to normally closed.
This applies to all 8536, 8538, 8539, 8606, 8630, 8640, 8736, 8738, 8739, 8810, 8940, 8941 devices.
