Details
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 124-198A 50/60Hz and the tripping class is 10A conforming to IEC 60947-4-1.
It can be direct mounted on EasyPact TVS contactors with directly connected by connector.
It protects unbalanced loads and motors with 132 - 280kW 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 Green Premium compliant (RoHs/Reach).
