DC 12 V Electronic Circuit Protector ESX10-TC

E-mail Print

Slim design – selective protection – remote control.

Technical Information:

Low voltage – but high safety requirements:

DC 12 V systems need to be protected reliably and selectively against overload and short circuit and in particular system parts which are powered by electronic DC 12 V switch-mode power supplies (SMPS) require electronic circuit protectors which exclude high fault currents by means of an integral current limitation. They keep the 12 V supply stable and prevent failures of connected loads. Due to its electronic trip characteristics the circuit protector ESX10-TC responds precisely and selectively. Short circuit currents will be limited to max. 1.8 times rated current; thus the SMPS will not even see the short circuit and will continue supplying the remaining system. Only the faulty path will be disconnected: fast, reliably and selectively.

Its robust, yet slim design with 80 mm height and depth and 12.5 mm width allows space-saving installation in control cabinets. The ESX10-TC is track-mountable and can be mounted side-by-side for multi-way protection concepts in any chosen number. The visual status indication and remote RESET and ON/OFF functionalities allow installation in hardly accessible areas and ex-protected outdoor systems in the petrochemical industry, which are often battery-buffered systems powered by solar modules.

12 V voltage levels for motor test stands and test equipment in car manufacturing or 12 V displays in steel industry and mechanical engineering also benefit from the ESX10-TC’s precision.
