Electronic circuit breaker type ESS20-0 is designed to ensure SELECTIVE disconnection of individual loads in systems which are powered by a DC 24V switch-mode power supply.DC 24V 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 al loads. As well as an unidentified failure this also means stoppage of the whole system.Through SELECTIVE disconnection the ESS20-0 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 ESS20-0 limits the highest possible current to 1.8 or 1.5 times the selected rated current of the circuit breaker. Thus it is possible to switch on capacitive loads of up to 75,000 uF lamp loads, but they are disconnected only in the event of an overload or short circuit. For optimal adjustment to the application conditions the current rating of the ESS20-0 can be selected in fixed values from 0.5A to 10A and in adjustable variants 1A/2A or 3A/6A. Failure and status indication are provided by a bicolor LED and an integral signal contact.The ESS20-0 also features a width of only 12.5 mm and can be plugged into the E-T-A Power Distribution socket Module 18Plus.Features:
