Schneider Electric — Motor Control
Schneider TeSys overload relays provide essential motor protection against overcurrent, phase loss, and phase imbalance. The LRD range offers thermal bimetallic overload protection with manual or automatic reset, adjustable current settings, and trip indication. The LR9 range provides electronic overload protection with wider adjustment ranges, selectable trip class, ground fault protection, and communication capabilities for SCADA integration. Both ranges mount directly to TeSys contactors for compact motor starter assemblies.
