Product description
Schneider Electric LRD04, part of the LRD sub-range, is a differential thermal overload relay designed for direct connection to a contactor with outgoing cables featuring screw-clamp terminals for the control circuit. This 3-pole device offers protection functions classified under Class 10A, with a rated current range of 0.4-0.63 A. It includes protection settings for thermal overload within the same current range. The LRD04 is equipped with 1 Normally Open (NO) and 1 Normally Closed (NC) auxiliary contacts. It supports a rated voltage (AC) for phase-to-phase connections up to 690 V at frequencies from 0 to 400Hz, with a minimum operating current of 0.4 A and a maximum of 0.63 A.
