Why Choose the BF12T4A400?
The Lovato BF12T4A400 is a robust four-pole contactor designed for reliable switching in industrial control panels. With an IEC AC-1 operating current of 28 A and a 400 VAC 50/60 Hz AC coil, it delivers dependable performance across diverse applications. Rated AC-3 at 12 A/5.7 kW (400 V), it supports motor loads while maintaining compact installation via screw or 35 mm DIN-rail mounting.
Built for demanding environments, the BF12 series offers 690 V rated insulation (Ui) and 6 kV impulse withstand (Uimp), with mechanical life to 20,000,000 cycles. Operating from −50 to +70 °C and up to 3000 m altitude, it meets IEC/EN/BS, UL and CSA standards. Terminal tightening torque of 1.5–1.8 Nm and pollution degree 3 support safe, consistent performance in panel assemblies.
