Product details

The LRD3359 is a differential thermal overload relay with a 48–65 A adjustment range and Class 10A trip class. The relay includes phase failure sensitivity: if one phase drops to zero, the relay trips at 130 % of the current setting on the remaining two phases, preventing single-phasing damage.

No direct sibling within the same adjustment range is listed for comparison; the LRD3359 occupies the 48–65 A slot in the TeSys Deca family. For lower or higher currents, adjacent order codes exist but fall outside this relay's coverage.
