Why Choose the BF3800A400?
The Lovato BF3800A400 is a robust three‑pole contactor designed for dependable motor and load switching. Rated 38A (AC3) at 400V with a 400VAC 50/60Hz coil, it suits European panels and OEM builds. Flexible screw or 35mm DIN rail mounting simplifies installation, while compliance with IEC/EN/BS 60947 standards supports reliable performance in industrial control applications.
Engineered for endurance, the BF38 series device delivers a mechanical life of 20,000,000 cycles and secure 2.5–3 Nm terminal torque. With Ui 690 V and Uimp 6 kV, it withstands demanding environments from -50 to 70°C and up to 3000 m altitude (pollution degree 3). UL/CSA 30 HP at 480 V broadens panel compatibility, complemented by a Sustainability certification.
