Electronic Circuit Breaker ESS20 Electronic circuit breaker type ESS20 is designed to ensure selective disconnection of individual loads in systems which are powered by a DC 24 V switch-mode power supply. DC 24 V power supplies, which are widely used in industry today, will shut down the output in the event of an overload with the result that one faulty load in the system can lead to complete disconnection of all loads. As well as an unidentified failure this also means stoppage of the whole system. Through selective disconnection the ESS20 responds much faster to overload or short circuit conditions than the switch-mode power supply. This is achieved by a combination of active current limitation and well-proven circuit breaker technology including physical isolation. The ESS20 limits the highest possible current to times the set rated current of the circuit breaker. Thus it is possible to switch on even capacitive loads or lamp loads, but they are disconnected only in the event of an overload or short circuit.

Electronic Circuit Breaker ESS20

Electronic circuit breaker type ESS20 is designed to ensure selective disconnection of individual loads in systems which are powered by a DC 24 V switch-mode power supply.

DC 24 V power supplies, which are widely used in industry today, will shut down the output in the event of an overload with the result that one faulty load in the system can lead to complete disconnection of all loads. As well as an unidentified failure this also means stoppage of the whole system.

Through selective disconnection the ESS20 responds much faster to overload or short circuit conditions than the switch-mode power supply. This is achieved by a combination of active current limitation and well-proven circuit breaker technology including physical isolation. The ESS20 limits the highest possible current to times the set rated current of the circuit breaker. Thus it is possible to switch on even capacitive loads or lamp loads, but they are disconnected only in the event of an overload or short circuit.

ESS20 Technical data Tambient = 25°C, operating voltage UB = DC 24 V

For optimal adjustment to the application conditions the current rating of the ESS20 can be selected by a switch 3 A or 6 A . Failure and status indication are provided by a bicolour LED and an integral signal contact.
