Alternate short-circuit protection

￭

Miniature circuit breakers (IEC)

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.
