Schneider Electric LR2K0305 Thermal Iec Overload Relay

Product Description

The SCHNEIDER ELECTRIC LR2K0305 is a thermal IEC overload relay rated for 0.54 to 0.8 amps with a maximum voltage of 690 VAC and 250 VDC. It operates on Trip Class 10A, providing fast motor protection against sustained overload conditions. This relay functions by sensing heat generated by excess current draw and tripping the circuit before motor windings sustain damage. It is designed for integration into motor starter assemblies and is typically installed by licensed electricians and industrial maintenance technicians working on motor control panels.

The LR2K0305 is suited for use in commercial and industrial motor control applications where IEC-standard components are specified. It is designed for use with LC1K, LC7K, LP1K, and LP4K contactor series, making it a direct-fit overload relay for those starter configurations. Typical install scenarios include conveyor drives, pump starters, fan motors, and other small motor loads requiring reliable overload protection in panel-mounted assemblies.

Key Features

• Thermal sensing method provides passive, reliable overload detection without external power
• Trip Class 10A rating for fast response to sustained overcurrent conditions
• Current adjustment range of 0.54 to 0.8 amps suits small fractional-horsepower motor loads
• Rated for 690 VAC and 250 VDC operation for broad voltage compatibility
• Compact form factor designed for direct mounting to IEC contactor series

Compatibility

Designed for use with LC1K, LC7K, LP1K, and LP4K IEC contactor series as a direct-mount overload relay.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements and local electrical codes. Disconnect and lock out all power to the motor control panel before removing or installing the relay. Verify the current setting adjustment is matched to the full-load amperage of the motor being protected before energizing the circuit. Do not energize the assembly without confirming proper seating of the relay on the contactor.
