It handles overload and short-circuit protection, earth fault detection, and phase failure sensitivity, with a manual reset. The unit is rated for 0.09 kW at 400...440 V AC 50/60 Hz, so it's sized for small motor loads like fans or pumps on a conveyor line. Control voltage is 24 V DC, with an operating range of 20...27 V DC and a drop-out threshold at 14.5 V DC. That means the coil holds reliably at 24 V nominal but drops out cleanly below 14.5 V, preventing chatter on a sagging supply. Typical current consumption is 60 mA sealed with a LUB12 base, spiking to 130 mA during closing — the control transformer or DC supply needs to handle that inrush. Rated operational voltage is 690 V AC, with insulation rated at 690 V per IEC 60947-6-2 and 600 V per UL 60947-4-1. The utilisation categories are AC-41, AC-44, and AC-43 — these cover motor switching with moderate to high inrush, so the unit is suited for direct-on-line starting of induction motors within its power band. The magnetic short-circuit release trips at 14.2 x Ir ±20%. Thermal overload protection follows Class 10 characteristics, temperature-compensated from -25 to 70 °C, matching IEC 60947-6-2 and UL 508 requirements. The LUCAX6BLTQ plugs into the front face of a TeSys U base (LUB12, LUB32, or LUB38), occupying 45 mm width on the DIN rail. IP20 on the front panel and wired terminals keeps it safe for enclosed panel mounting; IP40 outside the connection zone. Heat dissipation runs 2 W with a LUB12 base, 3 W with LUB32 or LUB38 — factor that into the panel thermal budget.","metaTitle":"Schneider LUCAX6BLTQ TeSys U Standard Control Unit, 24 V DC","metaDescription":"Schneider Electric LUCAX6BLTQ TeSys U standard control unit for motor protection. 24 V DC coil, 690 V AC rated, 0.09 kW at 400 V.
