An LRD Overload Relay is a thermal overload protection device used with motor starters to safeguard motors from excessive current, overheating, and prolonged overload conditions. It operates using a bimetallic strip that bends when exposed to high current, triggering a trip mechanism that disconnects the motor circuit to prevent damage. LRD relays from Schneider Electric are commonly paired with motor contactors and offer adjustable current settings, manual/auto reset options, and reliable protection for a wide range of motor applications.
Packard Engineering Ltd. offers a complete range of Schneider Electric TeSys LRD Overload Relays, starting from LRD01 up to LRD365 and extending to the higher-capacity models LRD3361 to LRD4369, along with heavy-duty LR9F5357 to LR9F7381 electronic overload relays. These overload relays provide reliable thermal protection for motors of various capacities, covering small fractional-kW motors up to large industrial loads. The LRD series includes adjustable current ranges, phase-failure protection, Class-10A tripping, and built-in manual/automatic reset options, while models like LRD3361, LRD365, and LRD4369 offer higher current settings from 48 A up to 140 A with robust auxiliary contacts (1 NO + 1 NC) and IP20 protection. LR9F electronic models provide wider adjustment ranges and enhanced precision for larger motors. All these Schneider Electric overload relays ensure dependable motor protection, easy mounting under compatible LC1D contactors, and long-lasting performance across demanding industrial environments.
