ABB busbars enable safe and economical cross-wiring of miniature circuit breakers, residual current devices and other modular DIN rail devices. For correct busbar selection, the following must be considered: terminal type (double terminal or cage terminal), number of poles of the devices (1, 2, 3, 4, 1+N or 3+N), device type (miniature circuit breakers, residual current devices or modular DIN rail devices), combinations of the different device types, use of miniature circuit breakers with auxiliary contacts mounted on the right and bottom, busbar connection cross-section (current carrying capacity), number of modules (selection from standard busbars or cuttable busbars)
