Schneider EasyPacts 4A Thermal Overload Relay LRE08

Thermal overload relay, Easy TeSys Protect, 2.5...4 A - class 10A
LRE08

The LRE relay is a differential thermal overload relays for use with fuses or magnetic circuit-breakers GV2 L and GV3 L. Its thermal setting range is 2.5-4A 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 screw clamp terminals connection. It protects unbalanced loads and motors with 1.1 - 1.5kW at 400VAC. It provides manual or automatic reset, trip auxiliary contact and flag indicator. Available worldwide, it is multi-standards certified (IEC, UL, CSA, CCC, EAC, Marine) and Environmental compliant (RoHs/Reach).
