BF50T4A024 Lovato contactor 4 pole AC3:50A 22kw 24VAC coil

Why Choose the BF50T4A024?

Engineered for reliable switching, the Lovato BF50T4A024 four‑pole contactor delivers robust performance in demanding control and power applications. With a 90 A AC1 rating and 50 A/22 kW AC3 at 400 V, this contactor handles substantial loads. A 24 VAC 50/60 Hz coil ensures versatile control compatibility, while screw or 35 mm DIN rail mounting speeds installation. The BF50 product designation aligns with Lovato’s industrial range for consistent specification and integration.

Built for endurance and safety, the BF50 series offers 1,000 V rated insulation (Ui) and 8 kV impulse withstand (Uimp) with Pollution Degree 3 for industrial environments. It delivers up to 15,000,000 mechanical cycles and operates from −50 to 70 °C up to 3,000 m altitude. Conformance to IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents, supports global panel standards. Terminal screws tighten to 4–5 Nm to maintain secure connections.
