BF1810A230 Lovato contactor 3 pole AC3:18A 7.5kw 230vac coil 1no aux

Why Choose the BF1810A230?

Lovato BF1810A230 is a robust three‑pole contactor designed for dependable motor and load switching. Rated 18 A AC3 at 400 V (7.5 kW) with 32 A Ith (AC1), it features a 230 VAC 50/60 Hz coil for universal control circuits. A built‑in 1NO auxiliary contact simplifies signalling, while screw or 35 mm DIN rail mounting speeds installation. It suits new panels and maintenance replacements.

Engineered for harsh environments, the BF18 series offers Ui 690 V and 6 kV impulse withstand, with reliable operation from −50 to 70 °C up to 3000 m altitude. Long life is assured with 20,000,000 mechanical operations. Compliance with IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents, supports global panel standards. Accessible terminals with 1.5–1.8 Nm tightening torque aid secure, repeatable connections.
