BF26T4D012 - 4P CONTACTOR NO 45A AC1 12VDC

Why Choose the BF26T4D012?

Lovato’s BF26T4D012 four‑pole contactor delivers dependable switching for motors and resistive loads. With IEC Ith (AC1) of 45 A and AC3 performance of 26 A/13 kW at 400 V, it suits a wide range of industrial control tasks. A 12 V DC coil ensures precise operation, while versatile screw or 35 mm DIN‑rail mounting speeds installation.

Engineered for endurance, the BF26 achieves a mechanical life of 20,000,000 cycles and operates from −50 to 70 °C. It offers Ui 690 V, Uimp 6 kV, and 15 HP at 480 V (UL/CSA). Rated for pollution degree 3 and installation up to 3000 m, it complies with IEC/EN/BS 60947 and equivalent UL/CSA standards.
