1 Electronic Circuit Breaker ES-0.. Description Electronic circuit breaker type ES-0.. is designed to ensure selective disconnection of individual loads in systems which are powered by a DC 4 V switch-mode power supply. DC 4 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 ES-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 ES-0.. limits the highest possible current to.8 or. times the selected rated current of the circuit breaker. Thus it is possible to switch on capacitive loads of up to 0,000 μf 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 ES-0.. can be selected in fixed values from 0. A... A and in adjustable variants A/ A or 3 A/6 A. Failure and status indication are provided by a bicolour LED and an integral signal contact. The ES-0.. features a width of only. mm and can be plugged into the E-T-A power distribution socket Module 7plus and SV/ SV4 (for ES-003) ensuring ease of installation and saving space in control cabinets. Features Selective load protection with physical isolation in the event of a fault. All types of loads can be connected (small DC motors etc. on request). Active current limitation (.8 or. times rated current I N = 8 A or A) for safe connection of capacitive loads up to 0,000 μf and on overload/short circuit. Electronic trip characteristic.

Electronic current limitation starts at typically.8 x I N *) which means that under all overload conditions (independent of the power supply and the resistance of the load circuit) the max. overload until disconnection will not exceed.8 x I N *) times the current rating. Trip time is between 0 ms (short circuit current I K ) and sec (at overload with high line attenuation). Without the current limitation activated at typically.8 x I N *) a considerably higher overload current would flow in the event of an overload or short circuit. After detection of an overload or short circuit the LED changes colour from GREEN to ORANGE. The LED will no longer be lighted after the circuit breaker has tripped. Resetting the circuit breaker is not possible before the integral bimetal has cooled down (approx. sec).

5 ES Accessories: Module 7plus Accessories for ES-0.. Description Module 7plus is a power distribution system for use with electronic circuit breaker ES-0... Each module accommodates two breakers with an individual housing width of only. mm and fits onto all industry standard mounting rails. The two-way modules can be interconnected to provide as many ways as required with a terminal block fitted at each end for connection of signalling circuits. A distribution busbar can be fitted on the supply side of the modules (positive pole) though each pole of multipole circuit breakers must be individually connected. Electrical connections are by means of spring-loaded terminals. The reference potential for the ES-0.. (Gnd pin ) is also looped through and connected to the terminals at the sides. The integral make contact of the ES-00 (-) can be tapped at terminal of the relevant channel (individual signalisation). The integral make contact of the ES-00 (-) can be tapped at terminal of the relevant channel (individual signalisation). The ES-003 has an integral signal contact (change-over contact). The contact -SO is used for group fault signalisation. For this purpose the contacts for signalisation are connected in series in the Module 7plus and are connected to the terminal blocks via two terminals (3,). It is possible with a test probe to contact the series connection in each module and detect possible interruptions. All internal wirings for the ground potential and the group signal are established by the modular mounting of the individual Modules 7plus.
