Alternate Short-Circuit Protection; Miniature Circuit Breakers (Iec Environment) - ABB ACS480 Hardware Manual

Alternate short-circuit protection



Miniature circuit breakers (IEC environment)

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 listed below. 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 with circuit
breakers not listed below. Furthermore, if the recommendations given by ABB are not
obeyed, the drive can experience problems the warranty does not cover.
Note: Miniature circuit breakers with or without fuses have not been evaluated for
use as short circuit protection in USA (UL) environments.
