Short-circuit protection (circuit breaker / disconnecting means)
Description
The motor starter is equipped with an integrated circuit breaker for short-circuit protection to
ensure that the system is safe and to protect personnel. Short-circuits between one phase
and ground (= ground fault) as well as between two phases are monitored.
Properties of the circuit breaker
The circuit breaker / disconnecting means is designed for the following functions:
● Disconnecting the series-connected starter and consumer from the supply voltage
● Closing lockout by means of a padlock on the rotating element
● Short-circuit protection for the series-connected consumer with circuit breaker
● Disconnecting the series-connected starter and consumer from the supply voltage
● Closing lockout by means of a padlock on the rotating element
● Short-circuit protection for the series-connected consumer with circuit breaker
Response when circuit breaker is OFF:
If a short circuit occurs or the circuit breaker is tripped manually, the motor starter responds
with a group fault.
