Thermal overload relay RE27D-12,5 004642410

Thermal overload relay – reliable motor protection

The RE27D-12.5 thermal overload relay is a key element in protecting electrical installations, primarily dedicated to protecting electric motors from overload. This device, manufactured by ETI Polam, provides effective protection against prolonged operation under excessive load, which translates to a longer lifespan and reliability of connected devices. This relay finds application in a wide spectrum of installations – from industrial to commercial and domestic.

Construction and functionality

The RE27D-12.5 relay is characterized by a flat plug-in connection, which facilitates its installation and integration with existing systems. The current setting range is from 8 to 12.5 A, allowing for precise adjustment to the characteristics of the protected circuit. It has one normally open (NO) auxiliary contact and one normally closed (NC) contact, enabling flexible control and device status signaling. Mounting can be done directly or independently, giving freedom in choosing the installation method. Class 10 release ensures appropriate sensitivity and speed of response to overloads.

Applications and benefits

This relay model is particularly useful in applications requiring reliable protection of motors with power adapted to the current setting range. Thanks to its design and functionality, the RE27D-12.5 minimizes the risk of damage caused by overloads, thereby reducing repair costs and downtime. A quick response to overload prevents more serious failures and ensures the continuity of the installation. For installers, this means easy installation thanks to the plug-in connection and the ability to precisely adjust parameters to specific application needs. The end user, in turn, gains confidence in the reliable protection of their electrical devices.
