Thermal Overload Relays—NEMA Rated

Solid State Overload Relay, Motor Logic® and Motor Logic Plus

Class 9065 / Refer to Catalog 9065CT9701

Motor Logic

Base Unit relays feature: 3 to 1 adjustment for trip current; phase loss and unbalance protection; direct replacement for Type S melting alloy; and LED power indication. They are ambient insensitive and self–powered. Electrical remote reset is also available.

Motor Logic SSOLR are designed to protect 50/60 hertz three-phase AC motors from overload, phase unbalance and phase loss conditions. Open Delta systems or grounded B-phase systems are difficult to balance and could cause the Motor Logic SSOLR to trip. For applications of this nature, it is recommended that bi-metallic overload relays (Form B12) be used.
