Product Description

The SCHNEIDER Overload Relay: Thermal Protection (SKU 3DY99, MPN LRD14) is an IEC thermal overload relay with integrated bimetallic elements, rated for 7 A – 10 A and a maximum voltage of 690V AC. It features a 1NO/1NC auxiliary contact form, screw clamp terminals, and phase loss sensitivity, and is compatible with TeSys Deca contactors (9 to 38 Amp models).

Frequently Asked Questions

What is the SCHNEIDER LRD14 overload relay used for?

The SCHNEIDER LRD14 is an IEC thermal overload relay that protects motors from overheating by monitoring current. It is used in industrial motor control applications, typically paired with TeSys Deca contactors (9 to 38 Amp models), to prevent damage from overloads or phase loss.

What are the specifications of the SCHNEIDER LRD14 overload relay?

The SCHNEIDER LRD14 has a current range of 7 A – 10 A, a maximum voltage rating of 690V AC, and a 1NO/1NC auxiliary contact form. It includes integrated bimetallic elements for thermal protection, phase loss sensitivity, and screw clamp terminals. It is compatible with TeSys Deca contactors.

Where to buy the SCHNEIDER LRD14 overload relay worldwide?

You can source the SCHNEIDER LRD14 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.

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

To select the correct SCHNEIDER overload relay, match the relay's current range (e.g., 7 A – 10 A for LRD14) to the motor's full-load current. Ensure compatibility with your contactor series, such as TeSys Deca, and verify voltage rating (690V AC) and phase loss sensitivity requirements.

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.
