BF12T4A57560 - 4P CONTACTOR NO 28A AC1 575/60

Why Choose the BF12T4A57560?

The Lovato BF12T4A57560 four-pole contactor combines robust performance with compact, panel-friendly mounting. Its 575 VAC 60 Hz coil and IEC AC1 rating of 28 A deliver assured switching for power and control circuits. With AC-3 performance of 12 A / 5.7 kW at 400 V and a 7.5 HP rating at 480 V (UL/CSA), it handles motors and resistive loads reliably in industrial installations.

Engineered for longevity and safety, the BF12 series offers 690 V rated insulation and 6 kV impulse withstand, a mechanical life of 20,000,000 cycles, and operation from -50 to 70 °C. Simple screw or 35 mm DIN rail mounting speeds installation, with 1.5–1.8 Nm terminal torque. Rated for up to 3000 m altitude and pollution degree 3, it conforms to IEC/EN/BS, UL and CSA standards.
