BF1801L024 - 3P CONTACTOR 1NC 18A AC3 24VDC LOW C.

Why Choose the BF1801L024?

Engineered for dependable motor control, the Lovato BF1801L024 three‑pole contactor delivers 18A AC‑3 at 400V (7.5 kW) with robust performance in industrial panels. This BF18 designation unit combines a low‑consumption 24 VDC coil with an integrated 1NC auxiliary mirror contact for reliable feedback and interlocking. SKU BF1801L024 supports screw or 35 mm DIN rail mounting for quick installation and panel flexibility.

Built for endurance and safety, the contactor offers 32 A Ith (AC‑1), 690 V rated insulation and 6 kV impulse withstand for robust isolation. It carries UL/CSA ratings including 10 HP at 480 V and a mechanical life of 20,000,000 cycles. Wide −50 to 70 °C operating range, up to 3000 m altitude, and Pollution Degree 3 suitability meet demanding UK industrial environments. Compliant with IEC/EN/BS 60947‑1 and 60947‑4‑1 standards.
