ABB 2CDL231001R1012 PS3/12 Phase rail 3Ph.,12Pins,10qmm

ABB Phase rails enable secure and economical cross-wiring of automatic fuses, fault current protection devices and other modular installation devices. The following must be taken into account for a correct phase rail selection: terminal type (double terminal or cage terminal), number of terminals (1, 2, 3, 4, 1+N or 3+N), type of device (automatic, fault current protection devices or modular installation devices), combinations of the different types of device, use of automatic fuses with auxiliary switches mounted on the right and the bottom, phase rail connection cross-section (current loadability), number of modules (extractable phases)
