BF12T4A04860 - 4P CONTACTOR NO 28A AC1 48/60

Why Choose the BF12T4A04860?

The Lovato BF12T4A04860 is a four-pole contactor engineered for dependable switching in industrial control and power circuits. Its 48VAC 60Hz coil provides consistent actuation, while a 28 A Ith (AC1) rating and 12 A/5.7 kW AC3 at 400 V support resistive loads and compact motor starters. With Ui 690 V and 6 kV impulse withstand, plus screw or 35 mm DIN rail mounting, it integrates quickly into new or retrofit panels.

Built to IEC/EN/BS 60947-1 and 60947-4-1 with UL/CSA approvals, this BF12 series device delivers confidence in demanding environments. It offers a 20,000,000-cycle mechanical life, operates from -50 to 70 °C up to 3000 m altitude, and specifies 1.5 to 1.8 Nm terminal torque. A 7.5 HP rating at 480 V (UL/CSA) and a Sustainability certification provide added assurance.
