An air compressor trips the circuit breaker when electrical supply limitations or mechanical resistance force the motor to draw current beyond the protection threshold. In this guide, we will analyze the causes of compressor overload trips and provide a step-by-step diagnostic method to help your equipment return to normal operation quickly.

Overload relays are devices that protect electric motors from overloads and phase failure. But what is overload protection? An overload occurs when the motor consumes too much current. Aside from the bimetallic strip and contacts indicated in the working principle section, there are a few other components in an overload relay worth mentioning. Observe the symbol of thermal overload relay below: Terminals 1, 2, 3, 4, 5 and 6 are power terminals Terminals 95 and 96 are trip contacts Terminals 97 an.

This guide explores the different types of protection relays and their testing procedures, with a focus on tools like secondary injection test sets and three-phase relay test sets. The testing and verification of protection devices and arrangements introduces a number of issues. Modern networks rely on and utilize relay protection systems in order to maintain a safe electrical environment by continuously monitoring devices for problems and controlling the grid to isolate problematic areas.
