BF3800L024 - 3P CONTACTOR 38A AC3 24VDC LOW C.

Why Choose the BF3800L024?

Lovato BF3800L024 is a robust three-pole contactor designed for dependable motor and load switching. Rated AC-3 38 A at 400 V (18.5 kW) with AC-1 56 A, it features a low-consumption 24 V DC coil for efficient control circuits. The compact BF38 series device mounts via screw or 35 mm DIN rail to streamline installation in control panels.

Engineered for demanding environments, it carries Ui 690 V and Uimp 6 kV ratings, operates from -50 to 70 °C, and achieves 20,000,000 mechanical cycles. Compliance with IEC/EN/BS 60947-1/-4-1, UL and CSA standards supports global panel builds. With 2.5–3 Nm terminal torque and mounting flexibility, integration is straightforward across OEM and maintenance applications.
