The Schneider Electric LP4K090083BW3 is a TeSys K 4-pole contactor with a 2 NO + 2 NC pole configuration, rated 20 A in AC-1 utilisation category at 690 V AC 50/60 Hz for resistive loads. Rated breaking capacity reaches 110 A at 415 V and 440 V, and 80 A at 500 V per IEC 60947 — meaning it can interrupt fault currents well above its continuous rating, which matters for coordination with upstream protection.
The power circuit average impedance is 3 mOhm at 20 A 50 Hz, so voltage drop across the contacts stays negligible even at full load. Operates in ambient temperatures from -25 to 50 °C and stores from -50 to 80 °C, with no derating required up to 2000 m altitude. Overvoltage category III and rated impulse withstand voltage of 8 kV mean it's suitable for fixed-installation panels connected to the mains supply.

Certified to EN/IEC 60947-4-1, GB/T 14048.4, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1. Rated insulation voltage is 600 V per UL 508 and CSA C22.2 No 14, and 690 V per IEC 60947-4-1. Flame retardance meets V1 per UL 94 and Requirement 2 per NF F 16-101/102.
