Overview
3-phase closed pin busbar (M6) is a shrouded/insulated pin-type copper busbar engineered for efficient and reliable three-phase power distribution. With a constant 17.8 mm pitch and 4 × 11.5 mm pin geometry, it supports compact layouts and neat wiring while keeping fingers safe during operation.
Standard lengths are 210 / 1000 / 1016 mm (modules 12 / 54 / 57), with reference current options from 50–80 A at up to 415 V. The color-coded, fire-resistant PVC jacket minimizes temperature rise and mis-wiring. The shrouded rail is finger-safe: DIN EN 50274, and the product complies with IEC 60664 and EN/IEC 60439-1.
