Motor Logic Solid-State Overload Relays

Motor Logic™ solid-state overload relays (SSOLRs) use an electronic method of detection, which responds directly to the motor current. When tripped, the overload relay can be reset manually, or remotely using the remote reset module. The SSOLR provides overload protection only for three-phase motors rated up to 600 Vac.

The SSOLR provides protection for phase-loss and phase-unbalance. In addition, this overload relay is ambient insensitive. The SSOLR is available as a selectable trip Class 10 or 20 device.

The Motor Logic SSOLR must be selected based on the Full-Load Amperage (FLA) of the motor it is to protect. Applications involving a motor with an FLA less than 1.5 A can be addressed by passing multiple looped turns of the motor leads through the current transformer windows.
