Schneider Electric LR2K0321 Thermal Iec Overload Relay

Product Description

The SCHNEIDER ELECTRIC LR2K0321 is a thermal IEC overload relay rated for 10 to 14 amps, 690 VAC, and 250 VDC. It uses a bimetal thermal sensing method to detect sustained overcurrent conditions and trip the connected contactor before motor windings or control circuit components sustain heat damage. Trip Class 10A defines the maximum trip time under overload conditions, making this relay appropriate for standard motor protection applications. Licensed electricians and industrial controls technicians install this device as part of motor starter assemblies in commercial and industrial panels. Its compact profile fits directly onto compatible IEC contactors without additional mounting hardware.

The LR2K0321 is designed for use in motor starter and control circuit assemblies where IEC-style components are specified. It is rated for Trip Class 10A service and suits applications running on 690 VAC three-phase systems or 250 VDC control circuits. The relay attaches directly to LC1K, LC7K, LP1K, and LP4K series contactors from Schneider Electric, making it a direct fit for existing starter assemblies using those contactor families. Typical installations include pump motors, conveyor drives, fan starters, and general industrial motor control centers.

Compatibility

Designed for direct use with Schneider Electric LC1K, LC7K, LP1K, and LP4K series contactors as stated by the manufacturer.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and applicable local codes. De-energize and lock out the panel before mounting or wiring the relay. Set the current adjustment dial to match the motor full-load amperage listed on the motor nameplate. Verify contactor and relay series compatibility before installation to ensure the direct-mount interface seats correctly.
