68 Guidelines for planning the electrical installation
Note : If the fuses for the drive protection are placed at the distribution board and the input
cable is dimensioned according to the nominal input current of the drive given in the rating
table on page
119 , the fuses will protect also 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. No separate fuses for the input cable protection are needed.
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.
You can use the circuit breakers listed below. Other circuit breakers can be used 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 that the warranty does not cover.
Note: Fuses must be used with circuit breakers in the USA.
1)
Maximum allowed rated conditional short-circuit current (IEC 61439-1) of the electrical power network
2)
Contact your local ABB representative
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.

Protecting the motor and motor cable in short-circuits
The drive protects the motor cable and motor in a short-circuit situation when the motor
cable is dimensioned according to the nominal current of the drive. No additional
protection devices are needed.
