Schneider Electric LRD332 Thermal Overload Relay

Schneider Electric LRD332 TeSys Deca thermal overload relay is a 3‑pole protective device for three‑phase motors, offering a selectable current range of 23 to 32 A to match motor sizing and control circuit needs. It is rated for use up to 690 VAC and provides a class 10A trip characteristic, delivering reliable protection against overload while minimizing nuisance trips on normal startup. This EverLink screw‑terminal version includes one normally open and one normally closed auxiliary contact (1 NO + 1 NC) to support signaling or simple interlocking within the control circuit. The LRD332 is designed to mount with Schneider Electric TeSys LR.D/Deca contactors, enabling compact, integrated motor protection within a single motor starter assembly. Typical applications include HVAC blowers, pumps, conveyors, and other commercial or light industrial motors where precise overload protection and straightforward wiring are essential. As part of the TeSys LR.D family, the LRD332 functions as a differential thermal overload relay that protects motors against sustained overload conditions, helping extend motor life and safeguard downstream equipment in Schneider Electric motor control schemes.
