Frequently Asked Questions

What is the SCHNEIDER IEC Overload Relay LR3D325 used for?

The SCHNEIDER LR3D325 is a three-pole thermal overload relay that protects motors from overheating due to sustained overcurrent. It is commonly used in industrial motor control panels, conveyors, pumps, and HVAC systems. The relay integrates bimetallic elements, so no external thermal units are required.

What are the specifications of the SCHNEIDER LR3D325 overload relay?

The SCHNEIDER LR3D325 is a 3-pole IEC thermal overload relay with a 1NO/1NC auxiliary contact form. It has screw clamp terminals, a maximum voltage rating of 690V AC, and is compatible with the TeSys Deca contactor series. It includes integrated bimetallic elements and does not offer phase loss sensitivity.

Where to buy the SCHNEIDER LR3D325 overload relay worldwide?

You can source the SCHNEIDER LR3D325 overload relay through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine SCHNEIDER components for motor protection applications.

How to install the SCHNEIDER LR3D325 thermal overload relay?

Mount the LR3D325 directly onto a compatible TeSys Deca contactor. Connect the motor leads to the relay's screw clamp terminals, ensuring torque meets SCHNEIDER specifications. Set the current adjustment dial to the motor's full-load amperage. Wire the 1NO/1NC auxiliary contacts into the control circuit for trip indication.
