BF1810L048 - 3P CONTACTOR 1NO 18A AC3 48VDC LOW C.

Why Choose the BF1810L048?

Engineered for reliable motor duty, the Lovato BF1810L048 three‑pole contactor combines a 48 V DC low‑consumption coil with AC‑3 performance of 18 A at 400 V (7.5 kW). Supplied with a built‑in 1NO auxiliary contact and screw or 35 mm DIN rail mounting, the BF1810L048 delivers compact, efficient switching for control panels and OEM machinery where low control power and strong IEC/EN 60947 compliance are essential.

Rated Ui 690 V and Uimp 6 kV, the BF18 series delivers robust insulation and surge withstand. This 32 A (AC‑1) device offers 10 HP at 480 V (UL/CSA), a mechanical life of 20,000,000 cycles, and operates from −50 to 70 °C up to 3000 m altitude. Screw terminals accept 1.5–1.8 Nm tightening; weight 500 g. Pollution degree 3, with 1NO auxiliary.
