BF50T4A230 Lovato contactor 4 pole AC3:50A 22kw 230VAC coil

Why Choose the BF50T4A230?

Lovato’s BF50T4A230 is a robust four-pole contactor engineered for demanding power switching. Rated Ith (AC1) at 90 A and Ie (AC3) 50 A / 22 kW at 400 V, it delivers dependable control of resistive and motor loads. A 230 VAC 50/60 Hz AC coil ensures straightforward integration into standard control panels, while suitability for photovoltaic applications adds flexibility across modern energy systems.

Built for longevity, the BF50 series offers 15,000,000 mechanical cycles, Ui 1000 V and Uimp 8 kV, with reliable operation from -50 to 70 °C. The BF50T4A230 mounts via screws or on 35 mm DIN rail for fast installation. It is rated 40 HP at 480 V (UL/CSA) and conforms to IEC/EN/BS 60947-1/-4-1, UL 60947-1/-4-1 and CSA C22.2 standards.
