BF1810D024 Lovato contactor 3 pole AC3:18A 7.5kw 24vdc coil 1no aux

Why Choose the BF1810D024?

Engineered by Lovato, the BF1810D024 is a compact three‑pole contactor designed for reliable motor and load switching. With an AC3 operating current of 18A at 400V (7.5Kw) and a robust 24V DC coil, it suits control panels and machinery requiring dependable performance. The built‑in 1NO auxiliary contact streamlines signalling, while flexible screw or 35mm DIN rail mounting simplifies installation and maintenance.

Rated Ui 690 V and Uimp 6 kV, this BF18 contactor combines durability and safety, with a mechanical life of 20,000,000 cycles and operation from -50 to 70 °C up to 3000 m. It meets IEC/EN/BS 60947 and UL/CSA standards, and features 32 A Ith (AC1). Terminal torque of 1.5–1.8 Nm ensures secure connections in demanding industrial environments.
