Overview
4-phase pin busbar (M6) is a pin-type copper rail for 4-pole modular power distribution on DIN-rail systems. It keeps a constant 17.8 mm pitch with 4 × 11.5 mm pin geometry for secure, low-resistance terminations on M6 terminals.
Standard lengths are 210 / 1016 mm (modules 12 / 56) with reference current choices from 50–80 A at up to 415 V. The color-coded, fire-resistant PVC jacket supports neat wiring and easy phase identification. Compliant with IEC 60664 and EN/IEC 60439-1, and produced under CE / ROHS / SGS / ISO 9001.
