BF11500A110 Lovato contactor 3 pole AC3:115A 55kw 110VAC coil

Why Choose the BF11500A110?

Lovato BF11500A110 is a robust three-pole contactor designed for demanding industrial switching. With an AC coil rated 110 V at 50/60 Hz, it delivers AC-3 performance of 115 A at 400 V and an Ith (AC1) current of 160 A. The BF115 series unit offers screw or 35 mm DIN rail mounting for straightforward integration in control panels and OEM assemblies.

Built for reliability, this contactor features 1000 V rated insulation and 8 kV impulse withstand, with a mechanical life of 15,000,000 cycles. It operates from -50 to 70 °C and up to 3000 m altitude. Conformity to IEC/EN/BS 60947, UL and CSA standards supports global acceptance, while 6–7 Nm terminal torque ensures secure, consistent connections.
