BF09T4A024 Lovato contactor 4 pole AC3:9A 4.2kw 24vac coil

Why Choose the BF09T4A024?

Designed for dependable switching, the Lovato BF09T4A024 is a four‑pole contactor with a 24VAC 50/60Hz coil and versatile mounting options. Delivering 25A Ith (AC1) and 9A/4.2kW AC3 at 400V, it suits general loads and motor duties. The BF09 platform integrates cleanly into panels via screw fixings or 35mm DIN rail. Rated insulation of 690 V and Uimp 6 kV support robust electrical performance.

Engineered for endurance, this contactor offers a mechanical life of 20,000,000 cycles and operates from −50 to 70 °C, with storage −60 to 80 °C and use up to 3000 m altitude (pollution degree 3). UL/CSA horsepower rating is 5 HP at 480V. Terminal tightening torque is 1.5 to 1.8 Nm. Conforms to IEC/EN/BS 60947‑1 and 60947‑4‑1, plus UL and CSA equivalents, with Sustainability certification.
