Description
The side walls have open slots through which wires leave to terminals and devices at any point along the run, and a removable cover closes the bundle and protects it from mechanical damage. The ducts are CR4025 (40×25 mm), CR4040 (40×40 mm) and CR6040 (60×40 mm), 2 m long, made of grey self-extinguishing insulating class M1 PVC, and are fixed to the panel with screws. The usable cross-section is 793 mm² (CR4025), 1354 mm² (CR4040) and 2040 mm² (CR6040), the ducts are for indoor installation, temperature code 321, and withstand a glow wire of 850 °C. In Multibox and Polibox cabinets they are placed on metal or perforated mounting panels together with DIN rails, terminal blocks and modular devices. The cross-section allows the fill of the duct with wires to be estimated, but does not replace a calculation of the run.
How to choose
The size is chosen by the number of wires in the bundle. CR4025 has the smallest cross-section, 793 mm², CR4040 gives 1354 mm², and CR6040 the largest, 2040 mm². The fill is best checked by calculation, since the cross-section serves only as a guide.
