8347 Description

Short technical summary and product information.

The HH Smith 8347 is an automatic, disc-type, quick-trip supplementary overload device. It is designed to sense and operate on locked rotor current, responding solely to motor current. These controls are intended to supplement motor winding thermostats in protection systems for hermetically-sealed compressors and three-phase motors.

 

Specific models include the 8347A21-12*, rated for 7-1/2 horsepower at 440V and 3-phase, and the 8348B13-4, rated for 15 horsepower at 440V and 3-phase. For 3-phase compressors, two supplementary overload devices are recommended.

 

These devices are crucial for providing adequate protection, especially on locked rotor conditions where temperature-responsive devices may not react quickly enough. They are suitable for use in protection systems for motors ranging from 2 to 12 horsepower.
