Compact starters are used primarily for switching and protecting motors. The actuator can be
used to switch the compact starter manually; together with the other display elements, it
shows the compact starter's current status.
The actuator has three positions:
●
READY: Compact starter is ready.
●
OFF: Compact starter is out of service.
●
TRIPPED: Malfunction or short circuit trip.

When the actuator is in the OFF position, the main contacts are open and the active areas
of the control electronics are disconnected. Only the thermal motor model and display
elements remain in operation.

adopt the following statuses:
