Its thermal protection adjustment range of 2.5...4 A covers small motor loads, and the Class 10A tripping curve means it will trip within 10 seconds at 7.2× the current setting — fast enough to protect standard induction motors during a locked-rotor event. The relay is supplied in a bulk quantity of 10, which is the standard packaging for this order code. The signalling circuit carries 3 A at 120 V AC-15 or 0.22 A at 125 V DC-13 — enough to drive a PLC input or a contactor coil through the 1 NO + 1 NC auxiliary contact block. The IP20 finger-safe enclosure is standard for panel-mount gear — no special handling needed inside a rated enclosure. Carries approvals across the major industrial regions: IEC 60947-4-1 and 60947-5-1, UL 60947-4-1 and 60947-5-1, CSA C22.2 No. 60947-4-1 and 60947-5-1, plus GB/T 14048.4/5 for China and EN 50495 for functional safety in potentially explosive atmospheres. This is a global-spec part — no regional variant needed.","metaTitle":"Schneider LRD08TQ TeSys Deca Thermal Overload Relay, 2.5-4A","metaDescription":"Active-production LRD08TQ differential thermal overload relay, TeSys Deca series. 2.5 to 4 A adjustment range, Class 10A, 690 V.
