Siemens overload relays are electrical protection devices designed to prevent motors and other equipment from overloading. They are an essential component in the industrial sector to ensure the longevity and safety of machinery and equipment.

The overload relay works by monitoring the current and temperature in the motor or equipment. If the current flowing through the device exceeds the maximum allowable value, the relay will trip and stop the machinery from functioning.

Siemens overload relays are highly reliable and efficient, and they are available in various models to suit different needs. They come in a variety of inputs, including thermal, electronic, and bimetallic, to ensure optimal performance.
