Electronic circuit breaker, signal contact: 1 N/C contact, nominal current: 10 A
Your advantages
Selective protection of all 24 V DC load circuits at switched-mode power supply units
A combination of active electronic current limitation in the event of short circuit and overload shutdown ensures that the circuit breaker can
respond to overloads faster than the switched-mode power supply unit
The residual current is always limited to 1.3 - 1.8 times the nominal current

Technical data
General
When mounted in rows without convection cooling, the nominal device
current should only be led to a maximum of 80% due to the thermal
effect during continuous operation (100% operating factor).
Special precautionary measures must be taken in systems or machines,
to prevent components from restarting (e.g., use of a safety PLC).
Parallel connection of multiple circuit breakers is not permitted.
