BF26T0A048 - 4P CONTACTOR NC 45A AC1 48V 50/60HZ

Why Choose the BF26T0A048?

The Lovato BF26T0A048 is a four-pole contactor engineered for dependable control in industrial panels. With a 48VAC 50/60Hz AC coil and a 4NC contact configuration, it delivers an IEC AC-1 Ith of 45A for resistive loads. Flexible installation is supported via screw fixing or 35mm DIN rail mounting, while robust terminals and compact construction streamline panel assembly and wiring in OEM, maintenance and upgrade projects.

Built for durability, the BF26 series offers a mechanical life of 20,000,000 cycles and operates from -50 to 70°C (storage -60 to 80°C). Rated Ui 690 V and Uimp 6 kV, it meets IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents. UL/CSA horsepower is 15 HP at 480 V. Pollution degree 3, max altitude 3000 m, and 2.5 to 3 Nm terminal torque support dependable performance.
