BF3800D048 - 3P CONTACTOR 38A AC3 48VDC

Why Choose the BF3800D048?

Lovato’s BF3800D048 is a robust three-pole contactor designed for reliable AC-3 duty. Handling 38 A (18.5 kW) at 400 V with a 48 V DC coil, it suits control panels needing precise, low-voltage control and dependable power switching. AC-1 current is rated at 56 A, and installation is flexible with screw or 35 mm DIN rail mounting for straightforward integration.

Engineered for endurance, the BF38 platform offers Ui 690 V and Uimp 6 kV, a mechanical life of 20,000,000 cycles, and dependable performance from -50 to 70°C. Rated Pollution Degree 3 and usable up to 3000 m altitude, it supports UL/CSA applications at 480 V (30 HP). Compliance with IEC/EN/BS 60947-1 and 60947-4-1 ensures straightforward integration and documentation.
