BF5000A400 Lovato contactor 3 pole AC3:50A 22kw 400VAC coil

Why Choose the BF5000A400?

The Lovato BF50 three‑pole contactor (SKU BF5000A400) delivers reliable switching for AC‑3 duty up to 50 A at 400 V, driven by a 400 VAC 50/60 Hz coil. Its compact design suits screw or 35 mm DIN rail mounting for fast panel integration. With 1000 V rated insulation and 8 kV impulse withstand, it provides robust performance across demanding industrial control applications.

Built for longevity and harsh conditions, the BF50 range offers 15,000,000 mechanical cycles, operates from −50 to 70 °C, and is rated for Pollution Degree 3 up to 3000 m altitude. It meets IEC/EN/BS 60947-1/-4-1 and UL/CSA equivalents, with 40 HP at 480 V, and secure 4 to 5 Nm terminal torque to simplify compliant, durable installations.
