BF26T2D125 - 4P CONTACTOR 2NO+2NC 45A AC1 125VDC

Why Choose the BF26T2D125?

Engineered for dependable switching in demanding panels, the Lovato BF26T2D125 four-pole contactor combines a 125 V DC coil with 2NO/2NC main contacts to handle AC-1 loads up to 45 A. The BF26T2D125 delivers robust insulation with Ui 690 V and Uimp 6 kV, and installs easily using screw fixings or 35 mm DIN rail. Its compact BF26 platform helps streamline builds while maintaining high performance across diverse control applications.

Built for longevity, this BF26 series contactor offers a mechanical life of 20,000,000 cycles and reliable operation from -50 to 70 °C, up to 3000 m altitude. It carries UL/CSA recognition including a 15 HP rating at 480 V, and complies with IEC/EN/BS 60947-1 and 60947-4-1. With 2.5–3 Nm terminal torque and a practical 670 g build, it suits robust industrial panel and OEM use.
