BF09T4D125 - 4P CONTACTOR NO 25A AC1 125VDC

Why Choose the BF09T4D125?

Lovato BF09T4D125 is a compact four‑pole contactor for dependable control and switching. With a 125VDC coil and AC1 rating of 25A, it also handles 9A/4.2kW at 400V in AC3 duty and 5 HP at 480V (UL/CSA). Easy screw or 35mm DIN rail mounting speeds panel integration, while the BF09 platform delivers robust performance for industrial automation and power distribution.

Engineered for resilience, it offers Ui 690 V and 6 kV impulse withstand, with reliable operation from -50 to 70 °C up to 3000 m altitude. A 20,000,000‑cycle mechanical life and 1.5–1.8 Nm terminal torque support long service. Conforms to IEC/EN/BS 60947-1 and -4-1, UL 60947-1/-4-1 and CSA C22.2 standards for assured compliance in demanding environments.
