BF18T0D220 - 4P CONTACTOR NC 32A AC1 220VDC

Why Choose the BF18T0D220?

Engineered for dependable switching, the Lovato BF18T0D220 four-pole contactor combines a 220 VDC coil with a robust AC1 rating of 32 A and AC3 performance of 18 A/7.5 kW at 400 V. The 4NC contact configuration offers assured isolation, while screw or 35 mm DIN rail mounting simplifies panel integration. With a Ui of 690 V and Uimp of 6 kV, it suits demanding industrial control applications.

Built to last, the BF18 series delivers 20,000,000 mechanical cycles and operates from -50 to 70 °C, with storage down to -60 °C. Rated for use up to 3000 m and pollution degree 3, it meets IEC/EN/BS 60947 and UL/CSA standards, with 10 HP at 480 V per UL/CSA. Ideal for UK control panels needing reliable four-pole switching on a 220 VDC control supply.
