NHP and WAGO have joined forces to release a range of terminal blocks for wire sizes ranging from 6mm² to 95mm².
The three versions of the WAGO 285 Series rail-mounted terminal blocks are suitable for applications with rated currents up to 232 A.
According to NHP, the larger the cable size, the more critical it is to clamp with the proper contact pressure. Therefore, even the most qualified electricians have to resort to a torque wrench.
This time consuming process can be avoided using WAGO terminal blocks where each wire, whether solid, stranded or flexible, ferruled or unferruled, is automatically clamped by the WAGO CAGE CLAMP or WAGO POWER CLAMP with the appropriate force throughout the entire cross section range.
The force is selected so that the cable is clamped precisely, without causing any cold flow deformations of the copper wires or other damaging effects.
According to the manufacturer, the spring can do even more, it compensates wire deformations over the entire lifetime of the terminal block and in addition is insensitive to temperature variations, vibrations and other types of shocks.
For the Series 285, WAGO has developed a variant of the WAGO POWER CLAMP which is designed to connect larger cable sizes.
All three 285 Series terminal blocks are said to be suitable for side entry wiring.
This means that, even larger cables, which are flexible to a limited degree, can be connected without a problem. A special feature makes it even easier: The clamps can be adjusted using one button in an open condition. Therefore the user can use both hands to insert the wires into the clamping position; at 95 mm², a real labour saving enhancement.
