The 3VA27 molded case circuit breaker or 3WL10 air circuit breaker as an MSP for starter
combinations
MSP for starter combinations with ETU320
● Use of the rating plug "L OFF" is not possible.
The overload protection "L" is set to the maximum slow setting.
● The instantaneous short circuit protection is max. 15x I
n
:
This cannot be increased during the switch-on phase.
It is therefore suitable for combining with 3RW soft starters or frequency converters because
they strongly limit the high inrush currents.
MSP for starter combinations with ETUs of the 6-series
● With use of the rating plug "L OFF".
The overload protection is deactivated:
● Deactivation of the instantaneous short-circuit protection "S"
Short-time-delayed short-circuit protection
ETU650 LSI
ETU660 LSIG
S Protection function can be ena-
bled/disabled
●
● Selection and parameterization of the setting options (current and time) for instantaneous
short-circuit protection for the switch-on phase (inrush adaptation) according to the
application.
