That means it's built for resistive loads — heaters, lighting banks, or any load where the current stays smooth through switching. The 24 V DC coil matches standard PLC or relay outputs, so it slots into a control panel without a separate power supply. Coil energisation takes 30–40 ms to close the NO contacts; de-energisation opens them in 10 ms. It carries approvals under IEC 60947-4-1, UL 60947-4-1, and CSA C22.2 No 60947-4-1, so it's accepted in North American and European panels without extra paperwork. The IP2X finger-safe housing means it's fine inside an enclosure but not for washdown areas. If you're switching motor loads (AC-3), you'll need to derate — this contactor is not specified for AC-3 duty in the evidence. The 24 V DC coil draws 3 W inrush and 3 W hold-in at 20 °C, with a 0.8–1.15 Uc operating range and dropout at 0.1 Uc. That's a tight hold margin, so verify your control supply doesn't sag below about 19 V DC. Breaking capacity is 110 A at 220–440 V, tapering to 70 A at 660–690 V. The associated fuse recommendation is 25 A gG or aM for the power circuit. Mechanical durability is 10 million cycles; electrical durability is 160,000 cycles at 20 A AC-1. That's a solid service life for a panel that cycles a few times per hour. Dimensions are 2.3 in (58 mm) high, 1.8 in (45 mm) wide, 2.2 in (57 mm) deep — compact enough for a crowded enclosure. Spring terminals accept 0.75–1.5 mm² solid or flexible wire. No built-in coil suppression module, so add a free-wheeling diode across the coil if driving from a DC output card.","metaTitle":"Schneider TeSys LP1K090043BD Contactor, 4P 20A AC-1, 24V DC","metaDescription":"Schneider TeSys LP1K090043BD contactor, 4 NO poles, 20 A AC-1 rated at 690 V, 24 V DC coil.
