Why Choose the BF1801D125?
The Lovato BF1801D125 is a compact three‑pole contactor designed for dependable control in demanding industrial panels. With an IEC AC‑3 rating of 18A/7.5kW at 400V and a robust 125V DC coil, SKU BF1801D125 delivers consistent switching performance. A built‑in 1NC auxiliary contact with mirror contact function supports reliable feedback signalling, while screw or 35mm DIN rail mounting simplifies installation in new builds and retrofit applications.
Engineered to IEC/EN/BS 60947 standards, the BF18 series contactor offers Ui 690V, Uimp 6kV and AC‑1 Ith 32A. It withstands -50 to 70°C operation, altitudes up to 3000 m and pollution degree 3, with a mechanical life of 20,000,000 cycles. UL/CSA ratings include 10 HP at 480V. Terminals tighten to 1.5–1.8 Nm for secure, vibration‑resistant connections.
