The Schneider Electric LP1K12004MPD is a TeSys K contactor with 4 normally-open poles, rated for 20 A in AC-1 utilisation category (resistive loads) at up to 690 V AC 50/60 Hz. The 230 V DC coil draws a 3 W hold-in power at 20 °C, with an inrush of 3 W at the same temperature. This is a compact 4-pole contactor — 45 mm wide, 58 mm tall, 57 mm deep — designed for rail or plate mounting in control panels.
The AC-1 rating of 20 A at 690 V means it is sized for resistive loads like heaters or lighting banks; it is not rated for motor duty (AC-3) in this variant. The 4 NO pole configuration gives you four independent normally-open switching paths, each rated for the same 20 A — useful for switching multiple resistive circuits simultaneously or for single-phase load grouping. The 230 V DC coil has an operational range of 0.8 to 1.15 times the control voltage, with dropout between 0.1 and 0.75 Uc below 50 °C — so the coil holds reliably at 184 V DC minimum and drops out cleanly below 172.5 V DC.
The LP1K12004MPD carries approvals under EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, GB/T 14048.4, and JIS C8201-4-1. The rated insulation voltage is 690 V per IEC 60947-4-1 and 600 V per UL 508 / CSA C22.2 No 14. The impulse withstand voltage is 8 kV, overvoltage category III. Flame retardance is V1 per UL 94, and it meets Requirement 2 of NF F 16-101 and NF F 16-102 for rail-vehicle fire behaviour. The safety reliability is quantified: B10d of 1,369,863 cycles under nominal resistive load and 20,000,000 cycles under mechanical load per EN/ISO 13849-1.
