BF26T4D220 - 4P CONTACTOR NO 45A AC1 220VDC

Why Choose the BF26T4D220?

Designed for reliable power switching, the Lovato BF26T4D220 is a four‑pole contactor with a 220VDC coil for DC control circuits. Delivering 45A AC‑1 and 26A/13kW AC‑3 at 400V, this compact unit suits demanding industrial loads. The BF26T4D220 offers screw or 35mm DIN rail mounting and conforms to IEC/EN/BS and UL/CSA standards for assured performance.

Built on the BF26 platform, this contactor provides Ui 690V insulation and 6kV impulse withstand for robust isolation. A 20,000,000-cycle mechanical life supports long service, while terminals tighten to 2.5–3 Nm. Rated for -50 to 70°C operation and installation up to 3000 m, it suits harsh environments under pollution degree 3.
