Why Choose the BF4000A024?
Engineered for dependable motor switching, the Lovato BF4000A024 is a three-pole contactor designed for AC-3 duties up to 40A at 400V (18.5 kW). Its 24VAC AC coil (50/60Hz) ensures reliable actuation, while screw or 35mm DIN rail mounting simplifies panel integration. The BF4000A024 meets IEC/EN/BS 60947-1 and 60947-4-1 requirements, making it a robust choice for industrial control applications across demanding environments.
High insulation and endurance underpin performance: Ui 1000V, Uimp 8kV and Ith (AC1) 70A, with a mechanical life of 15,000,000 cycles. Rated for -50 to 70°C operation and up to 3000 m altitude, this BF40 series contactor offers 30 HP at 480V (UL/CSA) and supports Pollution Degree 3 environments. A sustainability certification and 4 to 5 Nm terminal tightening torque further support reliable, compliant installation.
