Product Description

The SCHNEIDER Overload Relay: Thermal Protection (SKU LRD22, MPN LRD22) is a 3-pole IEC thermal overload relay with integrated bimetallic elements, rated for 16 A – 24 A and a maximum voltage of 690V AC. It features 1NO/1NC auxiliary contacts, screw clamp terminals, and phase loss sensitivity. Designed for use with TeSys Deca contactors (25 to 38 Amp models), it requires no external thermal units.

Frequently Asked Questions

What is the SCHNEIDER LRD22 overload relay used for?

The SCHNEIDER LRD22 overload relay provides thermal protection for three-phase motors by monitoring current and preventing overheating. It is used in industrial motor control applications, typically paired with TeSys Deca contactors (25 to 38 Amp models), and includes phase loss sensitivity for enhanced motor protection.

What are the specifications of the SCHNEIDER LRD22 overload relay?

The SCHNEIDER LRD22 is a 3-pole IEC thermal overload relay rated for 16 A to 24 A with a maximum voltage of 690V AC. It features 1NO/1NC auxiliary contacts, screw clamp terminals, integrated bimetallic elements (no external thermal units required), and phase loss sensitivity. It is compatible with TeSys Deca contactors.

Where to buy the SCHNEIDER LRD22 overload relay worldwide?

You can source the SCHNEIDER LRD22 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 select the correct SCHNEIDER overload relay for a motor?

To select the correct SCHNEIDER overload relay, match the relay's current range (e.g., LRD22 covers 16 A to 24 A) to the motor's full-load current. Ensure compatibility with your contactor series (TeSys Deca for 25 to 38 Amp models). Verify voltage rating (690V AC) and required features like phase loss sensitivity. Always consult the motor nameplate.

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.
