BF18T4D012 - 4P CONTACTOR NO 32A AC1 12VDC

Why Choose the BF18T4D012?

The Lovato BF18T4D012 is a four-pole contactor for reliable industrial switching. With an IEC AC1 operating current of 32 A and a 12 V DC coil, this BF18 series unit delivers dependable control performance. Flexible mounting via screw fixings or 35 mm DIN rail streamlines panel assembly, while compact construction and Lovato quality help simplify installation and long-term service in control and automation applications.

Engineered for demanding environments, the BF18 contactor offers 18 A AC3 at 400 V (7.5 kW) and a 10 HP rating at 480 V (UL/CSA). High insulation levels (Ui 690 V, Uimp 6 kV) and a mechanical life of 20,000,000 cycles support durability. A broad operating range from -50 to 70 °C, storage down to -60 °C, pollution degree 3 and installation up to 3000 m ensure confident service across varied sites.
