Four-phase distribution boards
Common-feed connections across compatible four-phase modular protective devices using L1, L2, L3 and N pin terminals.
Pin-type four-phase copper busbars for compatible modular protective devices in distribution boards and control panels.
01 / PRODUCT VIEWThe P-4L series uses a 17.8 mm device pitch with 4 mm-wide, 11.5 mm-long pin contacts. Published configurations cover 210 and 1016 mm lengths, 12 and 56 modules, conductor cross-sections from 8 to 16 mm² and reference currents from 50 to 80 A. The drawing shows the repeating L1, L2, L3 and N sequence for four-phase distribution.
Choose the required conductor cross-section, finished length and module count. Dimensions B, C, D and F correspond to the published drawing; all dimensional values are in millimetres.

Common-feed connections across compatible four-phase modular protective devices using L1, L2, L3 and N pin terminals.
Organized four-phase power distribution where 17.8 mm pitch and the P-4L pin geometry are required.
Repeat panel builds selected by Article No., cross-section, module count and finished length.
Use the published model table and dimension drawing for initial selection, then request controlled documentation with your enquiry.
P-4L is the pin type 4-phase busbar range for L1, L2, L3 and N distribution. Select the published Article No. that matches the required cross-section, length and module count.
The Article No., conductor cross-section, module count, overall length and reference current vary by model. The 17.8 mm pitch, 4 mm pin width and 11.5 mm pin length remain the same in the supplied table.
