Ac Power Supply, Redundant; Technical Specifications Of The Telescopic Rails - Siemens SIMATIC Series Operating Instructions Manual

Note
Information on the dimensioning of the fuses in the higher-level plant circuits
A fuse, which is designed for a tripping current of typical 6.3 A, is integrated in the power
supply of the IPC. Pulse current are also taken into consideration by the "time lag" type. In
the case of fault, this fuse ensure the correct separation of the device from the power supply.
It is recommended to use a fuse of at least 6.3 A for the protection of the higher-level power
supply circuit in addition to the power requirement of the additional devices that are also
supplied through this circuit. The tripping characteristic of the higher-level protection must
hereby take into consideration the starting currents of the IPC and those of the other
devices.
