Thermal overload relay RE67.1D-50 004643416

Motor and Circuit Protection – Thermal Relay RE67.1D-50

The RE67.1D-50 thermal relay is a reliable device used to protect electric motors and circuits from overload. It provides effective protection against damage caused by excessive current draw, which translates to a longer lifespan of connected devices and minimizes the risk of downtime. It is a key element in electrical protection systems, both in industrial and commercial installations.

Functionality and Application

The device is designed to work with CEM/CEAM series contactors, forming an integral part of the motor starting system. Its main function is to monitor the current flowing through the circuit and disconnect the power supply if the set threshold is exceeded – thus protecting the motor from overheating and potential winding burnout. The current setting range of 32…50A allows the relay to be adapted to various applications and motor powers. The mounting method – direct or independent – provides flexibility in integration with existing infrastructure.

Design Features and Parameters

The RE67.1D-50 relay is characterized by a flat plug-in connection for the main contacts, which facilitates quick and safe installation. It has one normally open (NO) auxiliary contact and one normally closed (NC) contact, allowing for signaling of the device status or remote control of other system elements. Triggering class 10 provides an appropriate time-current characteristic, adapted to typical motor loads. The relay design is designed for reliability and durability, guaranteeing long-term and trouble-free operation even in demanding environmental conditions.
