Thermal overload relays are essential components in electrical systems, providing protection against overheating and potential damage. Among the leading brands in this field, Schneider Electric stands out with its LRD16 model. In this article, we’ll delve into the description, features, applications, and advantages of the Schneider LRD16 thermal overload relay, along with installation guides, troubleshooting tips, maintenance advice, and customer feedback.

Understanding Thermal Overload Relays

What are thermal overload relays?

Thermal overload relays are protective devices designed to prevent motors and other electrical equipment from overheating. They monitor the current flowing through the circuit and trip the circuit if it exceeds a preset value for a certain period, thus safeguarding the equipment from damage due to excessive heat.

How do they work?

Thermal overload relays operate based on the principle of thermal expansion. They contain a bimetallic strip or a heating element that responds to the current passing through the circuit. When the current exceeds the set threshold, the strip or element heats up, causing it to bend and trigger the relay to disconnect the circuit.
