Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LR3D10L) is a 3-pole IEC thermal overload relay from the TeSys Deca series, designed for use with TeSys Deca contactors (9 to 38 Amp models). It features integrated bimetallic elements, eliminating the need for separate thermal units, and provides a 1NO/1NC auxiliary contact configuration with screw clamp terminals. The relay has a maximum voltage rating of 690V AC and does not include phase loss sensitivity.

Frequently Asked Questions

What is the SCHNEIDER LR3D10L overload relay used for?

The SCHNEIDER LR3D10L is a 3-pole IEC thermal overload relay from the TeSys Deca series. It protects motors from overheating by using integrated bimetallic elements to trip the circuit when current exceeds safe levels, commonly used in industrial motor control panels.

What are the specifications of the SCHNEIDER LR3D10L overload relay?

The SCHNEIDER LR3D10L is a 3-pole thermal overload relay with 1NO/1NC auxiliary contacts, screw clamp terminals, and a maximum voltage rating of 690V AC. It is compatible with TeSys Deca contactors (9 to 38 Amp models) and includes integrated bimetallic elements, so no separate thermal units are needed.

Where to buy the SCHNEIDER LR3D10L overload relay worldwide?

3G Electric supplies the SCHNEIDER LR3D10L overload relay to customers worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this TeSys Deca series relay to your facility, ensuring compliance with international shipping requirements.

How to install the SCHNEIDER LR3D10L overload relay?

To install the SCHNEIDER LR3D10L, mount it directly onto a compatible TeSys Deca contactor (9 to 38 Amp models) using the screw clamp terminals. Ensure the motor full-load current is within the relay's adjustment range, and wire the 1NO/1NC auxiliary contacts into the control circuit per the wiring diagram.
