BF09T2A048 - 4P CONTACTOR 2NO+2NC 25A 48/50-60

Why Choose the BF09T2A048?

Lovato’s BF09T2A048 is a robust four‑pole contactor designed for reliable switching in industrial control panels. With a 2NO + 2NC configuration and an AC coil rated 48 VAC, 50/60 Hz, it delivers an IEC AC1 Ith of 25 A and AC3 performance of 9 A / 4.2 kW at 400 V. Flexible screw or 35 mm DIN‑rail mounting simplifies installation in compact assemblies.

Engineered to BF09 designation standards, this contactor offers 690 V rated insulation (Ui) and 6 kV impulse withstand (Uimp) for dependable isolation. It achieves a mechanical life of 20,000,000 cycles and operates from −50 to 70 °C. With pollution degree 3, storage to −60…80 °C and max altitude 3000 m, it complies with IEC/EN/BS, UL and CSA requirements for demanding environments.
