BF18T0L012 - 4P CONTACTOR NC 32A AC1 12VDC L.C.

Why Choose the BF18T0L012?

Lovato BF18T0L012 is a four-pole contactor (4NC) with a low-consumption 12 V DC coil, engineered for dependable control switching. Rated 32 A AC1 and 18 A/7.5 kW AC3 at 400 V, it suits motor duty and resistive loads. Screw or 35 mm DIN rail mounting simplifies panel build. With Ui 690 V and Uimp 6 kV, this contactor delivers robust insulation performance.

Built for endurance, the BF18 series offers 20,000,000 mechanical cycles and reliable operation from -50 to 70 °C. Pollution degree 3 and a 3,000 m max altitude rating support challenging sites. Compliance with IEC/EN/BS 60947 and UL/CSA standards ensures broad acceptability, while the compact 508 g unit integrates cleanly in control panels, supporting sustainability goals.
