Thermal overload relay RE27D-17 004642412

Thermal overload relay – protection for motors and installations

The RE27D-17 thermal overload relay is a reliable device used to protect electric motors from overload. Its function is to monitor the current flowing through the motor and trigger it when the permissible value is exceeded, preventing damage. This is a key element in ensuring the safety and long-term operation of electrical equipment.

Construction and application

The RE27D-17 relay is designed to work with motor starters of the CEM09…CEM25 series, forming an integral part of the protection system. It can be mounted directly on the starter or independently, providing flexibility in choosing a solution for a specific application. Flat plug-in connections facilitate quick and safe wiring.

• Current setting range: 11…17 A – allows precise adjustment to the load characteristics.
• Release class: CLASS 10 – ensures a quick response to overloads, minimizing the risk of motor damage.
• Auxiliary contacts: Has one normally open and one normally closed contact, which can be used to signal the device status or remotely disconnect the circuit.
• Mounting method: Direct/independent mounting – provides flexibility in choosing a solution for a specific application.

Benefits of use
