    Schneider Electric LRD22L TeSys D Thermal Overload Relay protects 9-11 kW motors at 400 V thanks to a thermal range of 16-24 A, trip class 20, and phase imbalance protection. LRD22L is a Schneider Electric TeSys LRD thermal overload relay for direct mounting on TeSys D contactors. With a thermal setting range of 16-24 A, trip class 20, and phase imbalance detection, it protects motors from 11 kW to 400 V.

    It has manual reset and test buttons, automatic reset, auxiliary trip contact, and flag indicator. It is available worldwide, certified to multiple standards (IEC, UL, CSA, CCC, EAC, Marine) and Green Premium compliant (RoHs/Reach). Thermal overload protection relay, bimetallic type, with phase imbalance protection (differential). Mounts directly to the lower terminals of a Tesys LC1D25-D38 contactor to form a compact starter.

    Light and compact, 45 mm wide. Temperature-compensated for good protection precision. Manual control with test and reset buttons, manual/auto reset selector switch. Trip signaling with 1 NO + 1 NC auxiliary contacts and trip display. Can be completed with terminal blocks for free-standing mounting (LAD7B, LAD96) and remote control devices (LAD703, LA7D03).
