Schneider Electric LRD07 Thermal Overload Relay

Schneider Electric’s LRD07 Thermal Overload Relay (MPN LRD07) provides adjustable motor protection with phase failure detection for three-phase motors in industrial control systems. Compatible with TeSys D contactors from LC1D09 to LC1D38, it can mount directly to the contactor or on a DIN rail and offers a current adjustment range of 1.6 to 2.5 A, a Class 10A relay, and 1 NO + 1 NC auxiliary contacts. Its phase-loss sensitivity and rated insulation voltage up to 690 VAC support reliable protection in motor control environments, making it suitable for use in motor starters for conveyors, pumps, compressors, and manufacturing equipment in industrial settings. Common replacements include ABB TA25DU-2.5 and Siemens 3RU2116-1CB0 thermal overload relays.
