Schneider Electric LR2K0305 Overload Relay 0.54-0.8 A 1NC/1NO

Schneider LR2K0305 Thermal Overload Relay

This Schneider Electric LR2K0305 is a thermal overload relay designed for motor protection in industrial control circuits. It mounts directly to compatible TeSys Deca and TeSys K contactors using screw clamp terminals. The unit provides adjustable thermal protection with a current setting range of 0.54 A to 0.8 A. It features a Trip Class 10A rating and offers both automatic and manual reset options.

For Panels Using TeSys Deca or K Contactors

This relay suits engineers maintaining or building motor starters with TeSys Deca or TeSys K series contactors where a 0.54 A to 0.8 A protection range is required. The 1NO/1NC auxiliary contacts integrate into standard control circuits rated up to 690 V AC or 250 V DC. Buyers needing a different current range, a solid-state protection principle, or a relay for non-TeSys contactor series should look at other models.

Adjustable 0.54 A to 0.8 A Current Setting

The decisive specification is the adjustable thermal trip range of 0.54 A minimum to 0.8 A maximum. This defines the motor full-load current the device can protect. If the application motor draws current outside this window, the relay will not provide correct overload protection. The Trip Class 10A timing and direct contactor mounting are fixed characteristics that accompany this range.
