The ABB 1SBN071305R1000, type LF16-4, is an insulated connecting strip accessory designed for ABB AF09–AF16 three-pole contactors. It enables parallel and series connection of contactor poles, providing flexible configuration options for increasing AC load capability or improving DC switching performance in industrial applications. ([new.abb.com](https://new.abb.com/products/1SBN071305R1000/lf16-4?utm_source=chatgpt.com))
The LF16-4 is equipped with a main terminal screw for connecting three contactor poles in parallel, allowing increased current flow through the parallel-connected poles. It can also be used for series connection of poles where increased DC voltage switching capability is required.
