The overload relay is also often called the 'thermal block' or 'thermal relay'. This part protects your compressor from self-destructing when things go wrong. When the current is too high for a too lo...

Frequent overload trips are not only annoying, but they are also a warning sign of potential problems. In this guide, we will analyze the causes of compressor overload trips and provide a step-by-step
The button you are repeatedly pressing on your air compressor is formally known as the thermal overload protector (TOP). This safety device is a thermal switch designed to sense
These steps help you identify why the relay trips and how to stop it from happening again. Let''s walk through the five most common causes of overload relay tripping and the fixes that
Because of the way the overload relay is contructed, it will trip quickly at a huge overload (within a second). But it will also trip on a small overload, this could even ben minutes or hours. Because of
When the electrical current exceeds the safe limit for the compressor motor, the overload relay heats up and eventually trips to cut the power. This action helps prevent potential damage to
Diagnose common industrial air compressor problems including low pressure, overheating, and moisture issues. View our troubleshooting checklist or find a local Kaeser service representative for support.
Many modern style three pole units may have phase loss protection to some degree, if so you likely need to pass current through all three poles to keep from tripping it on phase loss features.
Overload trip, also known as current overload protection, is one of the most common electrical failures in screw air compressors. Frequent overload shutdowns can interrupt production,
It is necessary to check the machine''s wiring to determine if there is a short circuit. Additionally, machine leakage can also cause the circuit breaker to trip, especially when the
This article explains the most common causes of breaker tripping in industrial compressor installations, including inrush current, protection selection, voltage drop, and mechanical resistance.
