The ControlPlex^® Rack system is the playfully flexible complete solution for DC power distribution and overcurrent protection in communication technology. The modular concept allows configurations to be tailored exactly to your individual requirements.

Like in a game with different building bricks, your customized solution is created from the components! Whether in the base game or at expert level – using our unique circuit breaker technology ensures precise overcurrent protection - always optimally adapted to your application.

Power-D-Box^® systems are ideally suited to power distribution, e.g. in telecommunications and data centres, in industrial power control systems for the chemical industry, oil and gas and for power engineering, environmental engineering, pharmaceuticals and foodstuffs as well as the steel industry.

he compact and flexible REX system is an all-in-one solution offering comprehensive DC 24 V protection and distribution options for machines and process control. It helps optimise the functionality and number of components.
The REX22D-T electronic circuit protector selectively protects all DC 24 V load circuits up to 20 A and limits the output current linearly during switch on or before tripping. The limitation cuts down the current rating in the event of a short circuit. This enables an effective and predictable protection even for switch mode power supplies with low power reserves.

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.
