The Telemecanique LR3D1322 is a bimetallic overload relay — the thermal element that sits between a contactor and the motor, protecting against sustained overcurrent by mimicking the motor's heating curve. It's classified under Relays > Solid State Overload Relays, with the broader category being Circuit Breakers, Fuses & Protection — which tells you this part lives in the motor branch circuit, not the control logic.
Sourcing Reality: Still in Production
Deployment Context
This bimetallic relay is designed to mount directly to a Telemecanique contactor — no separate DIN-rail footprint needed. It clips onto the contactor's base, sharing the same power connections through the contactor's output terminals. The thermal mechanism is field-adjustable, so you can set the overload trip current to match the motor nameplate without swapping the relay body. That's the kind of detail that keeps a panel builder from carrying a shelf of fixed-range spares.
