11.2.3 Cable protection and device protection
There are two possibilities to protect the cable and the device:
m Ca
ble protection fuses and semiconductor fuses, which are connected in series
m Use
all-range fuses with a tripping characteristic gR or gS (DIN VDE 0636-201 / IEC
60269-2-1 / HD 630.2.1 54).
The suitable cable and device protection fu
ses must be dimensioned dependent on the
interface of the used power supply cable, the peak current and of the required I

ZDevice protection– on page 191.
In contrast to the fuses, the devices and cables can be protected with listed „Circuit break-
ers“ complying to UL (DIVQ).
Permitted are circuit breakers without a tripping delay, only. Circuit breakers with only a
thermal tripping characteristic are not tested and therefore not permitted. It must be con-
sidered that the installation is protected against fire but not against destruction.
Dimension the circuit breaker dependent on the interface of the used power supply cable
as well as from the rated and the peak current of the devices.
