Product Description
The LRE relay is a differential thermal overload relays for use with fuses or magnetic circuit-breakers. Its thermal setting range is 51-81A 50/60Hz and the tripping class is 10A conforming to IEC 60947-4-1. It can be direct mounted on Easy TeSys Control contactors with directly connected by connector. It protects unbalanced loads and motors with 30-45kW at 400VAC. It provides manual or automatic reset, trip auxiliary contact and flag indicator. Available worldwide, it is multi-standards certified (CB scheme,CE,CCC,EAC) and Environmental compliant (RoHS/REACH).
Key Features
- Provide cost-effective and essential control & protection solution to a simple application
- Designed to protect motors against overloads, phase failure
