Schneider TeSys LRD LRD16 Thermal Overload Relay, 9–13A, Class 10A
Submit your RFQ. Our team will send a quotation confirming price and availability.
Schneider Electric LRD16 is a differential thermal overload relay for motor protection, with an adjustable 9–13 A range and Class 10A tripping. It provides phase-failure sensitivity, one normally open and one normally closed signalling contact, and front stop/reset controls. It mounts below the compatible TeSys contactors listed in the specifications; separate rail or plate mounting requires the specified accessories. Short-circuit protection must be coordinated separately.
