Technical data
Dimensions
The Current Protector is connected in the
primary circuit before the low-voltage trans-
former (e.g. AC 230 V/12 V). Irregularities in
the secondary circuit, such as overloads or
short-circuits, will cause the Protector to
immediately disconnect the system. Under-
load (e.g. defective terminal connections)
also causes system disconnection. Error
indication by red LED. After removal of the
fault, the system can be reconnected by
operation of the storage push button on the
Protector or by operating the light switch.
