BF80T4A400 Lovato contactor 4 pole AC3:80A 45kw 400VAC coil

Why Choose the BF80T4A400?

The Lovato BF80T4A400 is a four‑pole contactor engineered for dependable switching in industrial panels. With an IEC AC1 operating current of 115A and an AC3 rating of 80A/45Kw at 400V, it manages demanding loads with confidence. A 400VAC 50/60Hz coil and screw or 35mm DIN rail mounting streamline installation and control in standard three‑phase systems.

Built for resilience, this contactor offers Ui 1000 V and Uimp 8 kV, a mechanical life of 15,000,000 cycles, and operation from −50 to 70 °C. It carries UL and CSA ratings, conforms to IEC/EN/BS 60947 standards, and suits pollution degree 3 environments up to 3000 m altitude—ideal for reliable service in harsh or space‑constrained control assemblies.
