Product Description

The SCHNEIDER LRD12 is an IEC thermal overload relay with integrated bimetallic elements, designed for use with TeSys Deca contactors (9 to 38 Amp models). It features a 1NO/1NC auxiliary contact form, screw clamp terminals, and a maximum voltage rating of 690V AC. The relay includes phase loss sensitivity and requires no external thermal units.

Frequently Asked Questions

What is the SCHNEIDER LRD12 overload relay used for?

The SCHNEIDER LRD12 is an IEC thermal overload relay that protects motors from overheating and phase loss. It is used with TeSys Deca contactors (9 to 38 Amp models) in industrial motor control applications, such as pumps, fans, and conveyors.

What are the specifications of the SCHNEIDER LRD12 overload relay?

The SCHNEIDER LRD12 has 3 poles, a 1NO/1NC auxiliary contact form, and a maximum voltage rating of 690V AC. It includes integrated bimetallic elements for thermal protection, phase loss sensitivity, and screw clamp terminals. The current range is 5.5 A to 8 A.

Where to buy the SCHNEIDER LRD12 overload relay worldwide?

You can source the SCHNEIDER LRD12 overload relay from 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.

How to select the correct SCHNEIDER overload relay for a motor?

Select a SCHNEIDER overload relay like the LRD12 by matching its current range (5.5 A to 8 A) to the motor's full-load current. Ensure compatibility with the TeSys Deca contactor series and verify voltage rating (690V AC). The LRD12 includes phase loss sensitivity and integrated bimetallic elements.

Used in

Common applications for SCHNEIDER
Motor starting in conveyor systems — Schneider Altistart ATS 22 soft starters (e.g., ATS22D17S6U) reduce inrush current.
Speed control for industrial pumps — Schneider Altivar ATV320 VFDs (e.g., ATV320U55N4W) provide variable flow regulation.
Machine safety interlocking — Schneider XPSUAF13AP safety relays monitor emergency stop circuits on assembly lines.
Panel-mounted control stations — Schneider XB5 flush push buttons (ZB5AA5) serve as start/stop operators in MCCs.
Heavy-duty motor switching — Schneider LC1G150LSEA contactors handle 150 A loads in compressor and crusher applications.
Emergency stop actuation — Schneider 9001K mushroom-head push buttons (9001KR25R) provide red, momentary stop functions.
