Fuses
AC and DC fuses are given in chapter Ordering information.
Note: The recommended fuses are for branch circuit protection per NEC as required for
the UL approval.
Forced cooling is recommended for the AC fuses to keep the fuse temperature under
100 °C (212°F). Monitoring of cooling fan status or fuse temperature is also
recommended.
If the AC fuses are located in another cabinet (eg, ICU), the suitable fan unit for AC fuse
cooling depends on the cabinet design. It is recommended to install the fan in such a way
that it directly cools the fuses.
See an example solution for fuse cooling and cooling fan status measurement on page 60.
