3.2.3 Fuses, Circuit Breakers and Power Supply Capacity
The CFW900 is suitable for use in circuits with short circuit capacity of up to 65 kA, which value varies according
to the type of protection used (fuse or circuit breaker) and certification considered (UL or CE). For more details,
see
,
and
For IEC conformity, fuses with rated current and I
2
t less than or equal to the values presented in the
(this table also presents suggestions for WEG fuses) or circuit breakers in the inverter power supply according
to the specifications presented in
When a circuit breaker is used, it is necessary to install the inverter
inside a metal panel with minimum dimensions according to the values shown in
Some models of
fused-protected inverters also require the use of a metal panel - for more details see
For UL conformity, fuses must be used in the inverter power supply as shown in
or circuit breakers in
the inverter power supply as shown in
Pay attention to the use of a panel, which is required for some
inverter models protected with fuses and for all inverter models protected by circuit breaker.
