Hardware Manual

76 Planning the electrical installation
Size the fuses at the distribution board according to instructions given in chapter
Technical data. The fuses will protect the input cable in short-circuit situations, restrict
drive damage and prevent damage to adjoining equipment in case of a short-circuit
inside the drive.
Circuit breakers
The protective characteristics of circuit breakers depend on the type, construction
and settings of the breakers. There are also limitations pertaining to the short-circuit
capacity of the supply network. Your local ABB representative can help you in
selecting the breaker type when the supply network characteristics are known.
Note: Circuit breakers must not be used without fuses in the USA.
WARNING! Due to the inherent operating principle and construction of circuit
breakers, independent of the manufacturer, hot ionized gases can escape from
the breaker enclosure in case of a short-circuit. To ensure safe use, pay special
attention to the installation and placement of the breakers. Obey the manufacturer’s
instructions.
ABB has tested these circuit breakers with the drive. Fuses must be used with other
circuit breakers
