BF2510A400 Lovato contactor 3 pole AC3:25A 12.5kw 400vac coil 1no aux

Why Choose the BF2510A400?

Choose the Lovato BF2510A400 three-pole contactor for dependable motor and load switching in industrial panels. Rated AC-3 25A (12.5 kW) at 400V with an AC coil 50/60Hz at 400VAC, it includes a built-in 1NO auxiliary contact for signalling. The BF25 platform installs by screw or 35mm DIN rail, and offers Ui 690 V and 6 kV impulse withstand for robust insulation performance.

Designed for demanding environments, it is rated for mechanical life of 20,000,000 cycles and operates from -50 to 70 °C, up to 3000 m altitude, pollution degree 3. Terminals tighten to 1.5–1.8 Nm for secure connections. Compliance with IEC/EN/BS 60947 and UL/CSA standards, plus a 15 HP rating at 480 V, supports control panel specifications.
