Thermal overload relay, EasyPact TVS, 5.5-8A, class 10A LRE12

Motor protection with EasyPact TVS thermal overload relay

This thermal overload relay, with a current setting range of 5.5-8A and a class 10A, provides reliable protection for electric motors against overloads and phase failure. Designed to work with fuse holders or magnetic trip units of the GV2L and GV3L series, it is a basic element of protection in many industrial and domestic applications. Direct mounting on Easy TeSys Control contactors with screw terminals ensures easy installation and integration with existing systems.

Functionality and application

The LRE12 relay protects motors up to 3 kW at 400 V AC, reacting to phase asymmetry and overloads. It has a built-in reset button, allowing manual reset after activation, as well as an auxiliary contact (1NO + 1NC) to indicate the status. This informs the user of any problems with the circuit. Use in industry, workshops or construction guarantees long-lasting and safe operation of devices.

Construction and characteristic features

The device is characterized by a solid construction and high quality of workmanship, confirmed by compliance with IEC 60947-4-1 standard. It provides effective protection against overload and short circuit - like most circuit breakers in this class. It is worth noting its compact dimensions (44.5 x 45 x 70 mm) and low weight (0.13 kg), which facilitates mounting even in tight spaces. Additionally, the presence of a trip indicator allows for quick identification of the cause of the failure. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
