The 1 NO + 1 NC auxiliary contact composition gives one normally-open signal for a PLC input (run indication) and one normally-closed for the safety chain (trip alarm), which is the conventional wiring for a motor starter. ## Standards and deployment context IEC 60947-4-1 is the standard for contactors and motor-starters; IEC 60947-5-1 covers control-circuit devices. This means the relay is accepted for use in IEC and UL 508A panels worldwide. The phase failure sensitivity — tripping at 130% of Ir on two phases with the third at zero — catches a lost phase before the motor single-phases and burns out, which is the critical protection for three-phase motor loads on a line. Mounting support is plate, rail, or under contactor, so it fits the standard DIN-rail footprint in a panel or directly on the contactor body for a compact starter assembly.","metaTitle":"Schneider Electric DPER365 Easy TeSys Differential Thermal O","metaDescription":"DPER365 differential thermal overload relay, Easy TeSys range. 48-65 A adjustment, Class 10, 1 NO+1 NC aux.
