Industrial LRD3363 Proximity Sensor Module Series

LRD3363 is Schneider Electric’s TeSys D thermal overload relay, a three‑pole protection device designed to guard 3‑phase motors by interrupting current when the preset setting is exceeded. It offers an adjustable current range of 63–80 A with a trip class of 10 A and is suitable for motor protection in systems up to 690 V, typically used with TeSys D contactors LC1D65 through LC1D95. The unit can be mounted directly to a contactor or used as a standalone protection relay, and it provides one normally open and one normally closed auxiliary contact for fault signaling. Electrical terminations are screw/clamp style for both upstream and outgoing cables, and the device weighs about 0.5 kg. Typical motor protections reference around 37 kW at 400 V, aligning with common TeSys D installations.
