Schneider TeSys K LP1K12004JD3 Contactor, 4P 4NO, 20A AC-1,

For motor loads (AC-3 duty), this unit is not rated — select a TeSys K variant with AC-3 utilisation category instead. The 4 NO pole configuration gives four independent switching paths, all closing on coil energisation, suited for three-phase plus neutral or four independent resistive circuits. Rated breaking capacity reaches 110 A at 440 V, 80 A at 500 V, and 70 A at 660…690 V per IEC 60947, so it interrupts fault currents well above its continuous rating. The rated making capacity is 144 A AC for the power circuit. Impulse withstand voltage is 8 kV (Uimp), and insulation voltage (Ui) is 690 V per IEC 60947-4-1, 600 V per UL 508 and CSA C22.2 No 14. Coil operating limits are 0.8…1.15 Uc for pick-up and 0.1…0.75 Uc for drop-out at under 50 °C. Operating time is 30…40 ms for coil energisation and NO closing, 10 ms for de-energisation and NO opening. Maximum operating rate is 3600 cycles per hour. Mechanical durability is 10 million cycles. For safety applications, B10d is 1,369,863 cycles with nominal load and 20,000,000 cycles with mechanical load per EN/ISO 13849-1.
