Overload Relay for TeSys Contactors

Schneider Electric LR2K0306 is a thermal overload relay rated 0.8 to 1.2 A with 1NO/1NC auxiliary contacts. It mounts directly on compatible TeSys Deca or TeSys K contactors using screw clamp terminals. Suitable for industrial motor protection panels requiring IEC-style relay coordination.

Trip Class and Voltage Limits

Trip Class 10A defines the thermal response curve for overload detection. The signalling circuit is rated to 690 V AC and 250 V DC, so control wiring must stay within these limits. The relay has three poles and auto or manual reset selectable on the device.

Current Setting Range Decides Fit

The adjustable range of 0.80 A minimum to 1.2 A maximum is the single figure that determines whether this relay matches the motor full-load current. If the motor draws outside this band a different relay must be chosen.

Questions about this item

Should I pick the 0.8 A minimum or the 1.2 A maximum setting for my motor?

The relay adjusts continuously between 0.8 A and 1.2 A; set the dial to match the motor's full-load current shown on its nameplate.

What does the 1.2 A maximum setting actually protect in a live circuit?

It trips the contactor when current exceeds 1.2 A for the Trip Class 10A time curve, stopping motor overheating.

How do the 250 V DC and 690 V AC ratings limit where I can wire the auxiliary contacts?

The 1NO/1NC signalling contacts must stay below 250 V DC or 690 V AC; they cannot switch mains power directly.
