Electronic Circuit Breaker with reset input ESS0-.. Description The special device ESS0-.. is a further extension of the product line electronic circuit breakers. Type ESS0-.. has a width of only. mm and selectively protects all DC 4 V loads through a combination of active electronic current limitation and well-proven circuit breaker technology including physical isolation and manual actuation. The ESS0-.. can be plugged into the E-T-A power distribution socket Module 7plus, ensuring ease of installation and a significant reduction of wiring time. DC 4 V switch-mode power supplies ( A...40 A), which are widely used in automation 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. The ESS0-.. helps to overcome this problem as it responds to the overload condition faster than the switch-mode power supply. The highest possible overcurrent is limited to.8 or. times rated current. Thus it is possible to switch on capacitive loads up to 0.000 μf 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 ESS0-.. can be selected in fixed values from 0. A... A and in switchable variants A/ A or 3 A/6 A. Failure and status indication are provided by a bicolour LED and an integral short-circuit proof signal output. Upon detection of overload or short circuit in the load circuit the MOET of the load output will be blocked and current flow in the load circuit will be interrupted. MOET and load circuit may be reset by means of the electronic reset input or manually by actuating the push-button (PUSH-PUSH operation). The load circuit may also be physically isolated during start-up of the equipment, e. g. for measuring purposes.

ESS0-.. - Accessories: Module 7plus Accessories for ESS0-.. Description Module 7plus is a power distribution system for use with electronic circuit breaker ESS0-.. 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 ESS0-.. (GND pin ) is also looped through and connected to the terminals at the sides. The integral signal output of the ESS0- may be picked off at terminal of the corresponding channel (single signalisation). The reset input may be connected via terminal 3 or.
