Issue:
Can 9065 Solid state overload relays be used in applications with Open Delta or Grounded B-phase systems?

Product Line:
NEMA Contactors and Overload relays

Environment:
9065 Motor Logic Solid-State Overload Relays

Cause:
The overload is tripping when used on Open Delta or Grounded B-phase systems

Resolution:
Open Delta systems or grounded B-phase systems are difficult to balance and could cause the Motor Logic SSOLR to trip. For these systems, it is better to use a Melting Alloy Overload Relay.
