Product Description

The SCHNEIDER LRD16 is a three-pole IEC thermal overload relay with integrated bimetallic elements, requiring no external thermal units. It features 1NO/1NC auxiliary contacts, screw clamp terminals, and a maximum voltage rating of 690V AC. Designed for phase loss sensitivity, it is compatible with TeSys Deca contactors in the 12 to 38 Amp models.

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.
