PS3/12 FI Busbar

ABB rails enable safe and economical cross-coupling of circuit breakers, ground current protection devices and other modular installation units. The following must be observed for the correct choice of phase bus rail: terminal type (dual terminal or cage terminal), number of poles in the units (1, 2, 3, 4, 1 + N or 3 + N), unit type (switches, ground current protection devices or modular installation units) , combinations of the different device types, use of automatic switches with auxiliary switches installed to the right and below, phase connection cross section (current load capacity), number of modules (choice from standard busbars or busbars that can be shortened)
