IDC-based power connection

The FieldPower product concept is based on the PowerBox, which is used to contact 5-pole power cables ranging from 2.5 to 6 mm2. The PowerBox integrates the following functions in a single module: power supply, extension, outgoing motor feeder and distribution. The PowerBox is mounted at any point within the plant with the continuous, uncut cable placed inside. Thanks to colour coding this is done quickly and without errors. Round and/or flat cables can be utilised. Using a sheath stripping tool, the cables are partially stripped and the individual cores are placed into the base module of the connection block and the contact unit snapped shut. Using a screwdriver, the contact element is simply closed downwards in a 90° movement. This creates a safe and reliable contact for distributing 400 V of power. The connection is made utilising IDC connection technology.

Junctions and outgoing circuits to loads such as starters or frequency converters can be implemented as fixed or pluggable variants with a current carrying capacity of up to 41 A. All that is required is to directly insert the insulation-stripped cores of the corresponding cable into the push in connection of the contact block or plug-in connector. The connector is simply plugged onto the contact block. One or two starters/frequency converters or other loads can be connected to the contact block. The PowerBox Fuse for ¼ x 11/4" fuses (cartridge fuse links) are utilised to protect loads, outgoing feeders and junctions. Visual control of the fuses is provided by a red LED that indicates failure.
