The coil is wound for 660...690 V AC at 50/60 Hz, drawing 30 VA inrush and 4.5 VA hold-in at 20 °C. It's a control contactor, sized for switching resistive loads in panels where four independent NO circuits are needed. The AC-1 rating of 20 A at 690 V means it handles resistive loads like heaters or lighting banks at that current; for motor loads (AC-3), the rating would be lower, though the ledger doesn't give that figure directly. The 660...690 V coil voltage is unusual — most control circuits run 110...240 V or 380...480 V — so verify your control transformer taps before specifying. The 4-pole, 4 NO configuration gives four independent switching paths, all normally open. That suits applications needing multiple isolated load circuits from one contactor, like switching several heater banks or lamp groups simultaneously. Mechanical robustness is rated for 10 Gn shocks on Y and Z axes with the contactor closed, and 4 Gn vibration at 5...300 Hz closed. That's enough for most industrial panel environments but not extreme mobile equipment. The 4-pole width matches a 45 mm module, so it occupies one standard 45 mm slot in a control panel. Heat dissipation is 1.3 W, negligible for panel thermal budgeting. The contactor carries approvals to EN/IEC 60947-4-1, UL 60947-4-1, CSA C22.2 No 60947-4-1, and JIS C8201-4-1, covering the main international and North American standards for contactors. It also meets GB/T 14048.4 for the Chinese market. Flame retardance is V1 per UL 94, and it passes NF F 16-101/102 for railway fire-smoke-toxicity requirements.","metaTitle":"TeSys K LC1K12004Y7 Contactor, 4P 20A AC-1, 660-690VAC Coil","metaDescription":"Obsolete TeSys K LC1K12004Y7 contactor. 4P (4 NO), 20A AC-1 at 690V, 660-690VAC 50/60Hz coil.
