Fuse protetion D.9T
D.9 Fuse protetion
It is to distinguish between the protection of the supply cables and the protection of the device. In order to
fulfill the CE specifications - here especially EN60204-1 - you have to protect the supply cables. Assure the
device in UL certificated installations.
NOTE
In UL-approved installations you must use the UL-listed semiconductor- or total-range-fuses.
D.9.1 Cable protetion
Place in safety fuses of the operation class gL DIN VDE 0636-201 / IEC 60269-2-1 / HD 630.2.1 54 or cable
protection switches with the triggering characteristic K referring to DIN VDE 0636-201 / IEC 60204-1 60269-
2-1 / HD 630.2.1 54, to protect the cables. These fuses protect against overloading and from consequential
damages from faults e. g. by fire. You cannot prevent, that the device is extensively destroyed, if a short circuit
or an ground fault occurs in the DC link.
Execute the protection according to EN 60204-1 (Electrical equipment of machines). Dimension the cable
protection fuses, dependent on the used cross section according to the valid national standards and local
regulations.
The current-carrying capacity of conductors is determined in table 5 of EN60204-1. For your operation you
must determine the a c cordant value in the standard on yourself, here an extraction:
