Product Description

The SCHNEIDER Overload Relay: Thermal Protection (MPN LRD3363) is a 3-pole IEC thermal overload relay with a 63 A – 80 A range, designed for use with TeSys Deca contactors (80 to 95 Amp models). It features 1NO/1NC auxiliary contacts, screw clamp terminals, a maximum voltage rating of 1000V AC, and phase loss sensitivity. The relay includes integrated bimetallic elements, eliminating the need for separate thermal units.

Frequently Asked Questions

What is the SCHNEIDER LRD3363 overload relay used for?

The SCHNEIDER LRD3363 is an IEC thermal overload relay that protects motors from overheating due to overcurrent or phase loss. It is used with TeSys Deca contactors (80 to 95 Amp models) in industrial motor control applications across machining, HVAC, and pumping systems.

What are the specifications of the SCHNEIDER LRD3363 overload relay?

The SCHNEIDER LRD3363 is a 3-pole thermal overload relay with a 63 A – 80 A range, 1NO/1NC auxiliary contacts, screw clamp terminals, and a maximum voltage rating of 1000V AC. It includes integrated bimetallic elements and phase loss sensitivity, requiring no separate thermal units.

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

Select a SCHNEIDER overload relay like the LRD3363 by matching its current range (63 A – 80 A) to the motor's full-load amperage. Ensure compatibility with your contactor series (TeSys Deca for this model) and verify phase loss sensitivity is needed for your application. 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.
