Frequently Asked Questions

What is the SCHNEIDER LRD350L overload relay used for?

The SCHNEIDER LRD350L overload relay provides thermal protection for three-phase motors by monitoring current and preventing overheating. It is used in industrial motor control panels, conveyors, pumps, and compressors. The relay includes phase loss sensitivity and integrates bimetallic elements for accurate trip response.

What are the specifications of the SCHNEIDER LRD350L overload relay?

The SCHNEIDER LRD350L is a 3-pole IEC thermal overload relay with a current range of 37 A to 50 A. It has 1NO/1NC auxiliary contacts, a maximum voltage rating of 690V AC, and screw clamp terminals. It includes integrated bimetallic elements, requires no thermal units, and is compatible with TeSys Deca contactors (40 to 65 Amp models).

Where to buy the SCHNEIDER LRD350L overload relay worldwide?

You can source the SCHNEIDER LRD350L overload relay worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. 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 to the motor's full-load amperage. The LRD350L covers 37 A to 50 A and is compatible with TeSys Deca contactors rated 40 to 65 Amps. Ensure the relay has phase loss sensitivity if the motor requires it. Always verify voltage rating (690V AC max) and auxiliary contact configuration (1NO/1NC).

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.
