The LP1K120045BD is a TeSys K contactor from Schneider, configured with 4 normally-open poles. It is rated for 20 A in AC-1 utilisation category (resistive loads) at up to 690 V AC, 50/60 Hz. The coil is 24 V DC, drawing about 3 W inrush and 3 W hold-in power at 20 °C.
For motor or inductive loads, you would need to derate to the AC-3 or AC-4 category; this contactor is specified only for AC-1 (resistive) duty, so it is not a direct fit for starting motors. The rated breaking capacity reaches 110 A at 440 V, 80 A at 500 V, and 70 A at 660–690 V per IEC 60947 — meaning it can interrupt fault currents up to those levels, which matters for coordination with upstream protection. Impulse withstand voltage is 8 kV, overvoltage category III, so it is rated for fixed-installation distribution panels.
