BF50T4A400 Lovato contactor 4 pole AC3:50A 22kw 400VAC coil

Why Choose the BF50T4A400?

Lovato BF50T4A400 is a four-pole contactor engineered for dependable control in industrial circuits. Its AC coil is rated 400VAC at 50/60Hz, delivering 90A IEC Ith (AC1) performance and 50A/22kW IEC Ie (AC3) at 400V for motor duty. Flexible screw or 35mm DIN rail mounting simplifies panel integration, and UL/CSA horsepower ratings list 40HP at 480V.

Built on the BF50 platform, this device combines robust electrical endurance and environmental resilience. It offers Ui 1000V and Uimp 8kV, a mechanical life of 15,000,000 cycles, and dependable operation from -50 to 70°C up to 3000 m, pollution degree 3. Conforming to IEC/EN/BS 60947-1/-4-1, UL 60947-1/-4-1 and CSA C22.2 60947-1/-4-1, it suits rigorous, standards-driven installations.
