DFW-2 Series
Cable Branch Box (EU)
Introduction
DFW series European Style Cable Distribution Box has significant advantages such as small length, clear cable arrangement, three-core cable, and no need for large span crossing. It is widely used in cable engineering equipment in power distribution network systems. The main feature of the DFW series cable distribution box is the two-way door opening, and the use of butt sleeves as the connection busbar. The cable connector used in the DFW series conforms to the DIN47636 standard, and generally uses a bolt-fixed connection cable connector with a rated current of 630A.
