BF50T4A110 Lovato contactor 4 pole AC3:50A 22kw 110VAC coil

Why Choose the BF50T4A110?

The Lovato BF50T4A110 is a robust four-pole contactor for dependable switching of AC-1 and AC-3 loads. With an AC coil rated 110VAC at 50/60Hz, it delivers an IEC Ith (AC1) of 90A and AC-3 performance of 50A/22kW at 400V. UL/CSA horsepower is 40HP at 480V, making it a versatile choice for industrial control panels and machinery requiring reliable, high-duty operation.

Installation is straightforward via screw fixings or 35mm DIN rail, and the BF50 platform offers high electrical resilience with Ui 1000 V and Uimp 8 kV. A mechanical life of 15,000,000 cycles, a -50 to 70 °C operating range, and use up to 3000 m ensure durability. Terminals tighten to 4 to 5 Nm. Conforms to IEC/EN/BS 60947, UL and CSA standards for assured compliance.
