1) "Utilization class 2" refers to the soft starter in combination with the protective device listed (circuit breaker/fuse), not to
other components in the branch. For utilization class, see page 10-20.
Standard circuit fused design with SITOR 3NE or 3NC semiconductor fuse
(semiconductor protection using fuse, line and overload protection using circuit breaker)
For suitable fuse bases, see LV1 catalog at
"SENTRON Switching and Protection Devices for Power Distribution" –>
"Switch Disconnectors" and ET B1 Catalog at "BETA Protecting" –>
