External AC Fuses ⎯ Recommended Rating
The site’s AC supply quality is of great importance. In general, a site with better AC supply quality
(stable nominal voltage) may use smaller breakers.
CAREFUL:
Minipack systems using 48V-400W rectifiers may also use the recommended external breakers specified in the 800W
Rectifiers table above, even though smaller breakers could be employed.
For more information, read document 2028364
WARNING:
Always replace a rectifier with blown internal AC fuse with a new module, and send the malfunctioning module for servicing.
WARNING:
You must always consider re-dimensioning the external AC fuses and AC cabling, before swapping 400W, 800W or
800W WIR Minipack rectifiers in the same Minipack system.

Notes:
• Use the values in {} brackets in the 185VAC column, if you are
unsure or know that the available AC mains voltage may drop
below 205VAC.
• Each phase feeds two 800W rectifiers
• The recommendations apply for use of Thermal magnetic circuit
breaker, type Siemens 5SX or 5SY series, MG C60H series or
similar. For more information regarding External AC fuses and
other types of fuses, please read the document 2024398.

Notes:
• Use the values in {} brackets in the 150VAC column, if you are unsure or know that the
available AC mains voltage may drop between 230VAC and 150VAC, or use the
values in [] brackets in the 100VAC column if the voltage may drop below 150VAC.
• Each phase feeds two 800W WIR rectifiers (Wide Input Range)
• The recommendations apply for following air breaker types:
- Up to 32A, use Melnrining DBN32 C char series or similar
- Bigger than 32A, use Melnrining DB47-63A C char series or similar.
For more information regarding External AC fuses and other types of fuses, please
