A supply line for the connected devices is often routed together with the communication busbars. There are special data protections with a higher nominal load current for these powerful lines. The main line is the HDTNV products, which offer high discharge ability, pluggable design and rated load current up to 1.5 A. These products are complemented by the solid DTNVE series and the HT series, which also includes Ethernet products, including PoE.
