Alternative short-circuit protection

Miniature circuit breakers (IEC)

If you use a miniature circuit breaker for the short-circuit protection of the drive, install
the drive into a metal enclosure.
Note: Miniature circuit breakers with or without fuses have not been evaluated for use
as short-circuit protection in North American (UL) environments.
The protective characteristics of the 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.
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.
You can use the circuit breakers specified by ABB. You can also use other circuit
breakers with the drive if they provide the same electrical characteristics. ABB does not
assume any liability whatsoever for the correct function and protection of the circuit
breakers not specified by ABB. Furthermore, if the specifications given by ABB are not
obeyed, the drive can experience problems the warranty does not cover.
