Product Description

The Schneider Electric LRD332 is a reliable thermal overload relay from the TeSys LR-D series, providing inverse-time delayed protection for motors with normal starting characteristics. With adjustable current setting from 23 to 32 A and Class 10A tripping, it is ideal for medium motors up to ~15–18.5 kW @ 400 V. Features manual/automatic reset, phase failure sensitivity, and auxiliary contacts (1 NO + 1 NC) for signaling. Designed for direct mounting on TeSys D contactors (LC1D40A…D65A), it ensures space-saving assembly in motor starters and control panels.

Standard Features

  • 23–32 A adjustable range: Covers medium motors — precise protection for 11–18.5 kW @ 400 V applications.

  • Class 10A tripping: Standard for motors with normal starting — inverse-time delayed overload protection.

  • Phase failure & unbalance detection: Built-in sensitivity — protects against single-phasing and asymmetric loads.

  • 1 NO + 1 NC auxiliary contacts: For signaling trip status or interlocking — manual or automatic reset selectable.

  • Direct contactor mounting: Fits LC1D40A to LC1D65A contactors — quick assembly without extra wiring.

  • Global approvals: IEC/EN 60947-4-1, UL, CSA, CCC — accepted worldwide for motor control.
