ABB 2CDL240101R1020 PS4/20N phase rails 4PH.,20Pins,10qmm Phase modifier 1 pc(s)

ABB phase rails enable the safe and economical cross-wiring of circuit breakers, residual-current protective devices and other modular installation devices. For correct phase bar selection, the following must be observed: Terminal type (double terminal or cage terminal), pole number of the devices (1, 2, 3, 4, 1+N or 3+N), Device type (circuit breakers, residual current circuit breakers or modular installation devices), combinations of different types of equipment, use of circuit breakers with auxiliary switches mounted on the right and bottom, phase rails cross-section (current carrying capacity), number of modules (selection from standard phase rails or short phase rails)
