Its 230-240 V AC 50/60 Hz coil pulls in on a standard panel voltage, and the 20 A AC-1 rating at up to 690 V means it handles resistive heating elements, lighting banks, or transformer primaries without derating worries. The 1.3 W heat dissipation is low enough that you can pack it into a tight DIN-rail enclosure without cooking adjacent components, and the 3600 cycles/hour max rate suits frequent cycling applications like oven zone control. Rated breaking capacity hits 110 A at 440 V and 70 A at 690 V, so it clears fault currents safely within a 25 A gG or aM fuse limit. The 144 A AC rated making capacity handles the inrush when a cold resistive load energises. Coil hold-in power is only 4.5 VA, but inrush at pickup is 30 VA — make sure your control transformer or PLC output can deliver that surge without voltage sag. At 1.8 x 2.3 x 2.2 inches (45 x 58 x 57 mm), this contactor occupies minimal DIN-rail space — roughly the footprint of a small ice cube relay. The 4 NO poles give you four independent switching paths in one package, useful for splitting a load across phases or for multi-stage heater control. Operating altitude is 2000 m without derating; above that you'll need to reduce the rated current per IEC guidelines. The overvoltage category III rating means it's suitable for fixed-installation distribution panels, not just downstream equipment. ## Safety and reliability data For functional safety applications, the B10d value is 1,369,863 cycles under nominal resistive load and 20,000,000 cycles under mechanical load per EN/ISO 13849-1. That gives you a solid data point for calculating PFHd in a safety circuit. The contactor also meets V-0 flame retardance per UL 94 and passes shock and vibration testing per IEC 60068-2-27 and IEC 60068-2-6 — up to 15 Gn shock on the Y axis when closed, and 4 Gn vibration from 5 to 300 Hz.","metaTitle":"Schneider TeSys K LC1K12004U7 Contactor, 4P 20A AC-1, 230-24","metaDescription":"Schneider Electric TeSys K LC1K12004U7 4-pole contactor, 4 NO, rated 20 A AC-1 at 690 V, 230-240 V AC 50/60 Hz coil.
