SKU
LRE355
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 30-40A 50/60Hz and the tripping class is 10A conforming to IEC 60947-4-1.
It can be direct mounted on EasyPact TVS contactors with screw clamp terminals connection.
It protects unbalanced loads and motors with 18.5kW 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 Green Premium compliant (RoHs/Reach).
