Electronic circuit protector type ESX10 is designed to ensure selective disconnection of DC 24 V load systems.
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 ESX10 responds much faster to overload or short circuit conditions than the switch-mode power supply. This is achieved by active current limitation. The ESX10 limits the highest possible current to values between 1.3 to 1.8 times the selected rated current of the circuit protector. Thus it is possible to switch on capacitive loads of up to 20,000 µF lamp loads, but they are disconnected only in the event of an overload or short circuit.
For optimal alignment with the characteristics of the application the current rating of the ESX10 can be selected in fixed values from 0.5 A...16 A. Failure and status indication are provided by a multicolour LED and an integral short-circuit-proof status output or a potential-free signal contact.
The ESX10, with a width of only 12.5 mm, can be plugged into the E-T-A power distribution socket Module 17plus ensuring ease of installation and saving space in control cabinets.

For most industries, the accepted norm for unplanned downtime is 5% of operating time, which represents a direct, significant loss of revenue and therefore profit. But have you ever stopped to consider the true cost of downtime? Read the latest white paper from E-T-A to see how the integration of electronic circuit control technology can reduce the downtime of your 24VDC system designs.
An increase in the demand for energy worldwide has driven the search for alternative primary sources of energy, even to the most remote locations of the globe. Natural gas is considered the cleanest burning fossil fuel with minimal environmental impact. This white paper shares a real world example of how the integration of electronic circuit protection eliminates the need for widely used NEMA 7 enclosures.
