ESX10-TC-DC 12 V electronic circuit protector Description E-T-As ESX10-TC extends our product group of electronic overcurrent protection devices for DC 12 V applications. ESX10-T helps to save time and costs. The track-mountable circuit protectors standard version provides one channel in the current ratings 1 A through 10 A. By means of busbars, the modular device allows construction of multi-channelled solutions and configuration of single or group signalling. E-T-As ESX10-T electronic circuit protector is only 12.5 mm wide and selectively protects all DC 12 V load circuits, thereby increasing the uptime of machines and systems. This is achieved by a combination of active electronic current limitation in the event of a short circuit and overload disconnection typically from 1.1 times rated current. The ESX10-T responds faster than frequently used DC 12 V switch mode power supplies without tripping fast and ESX10-TC thus prevents disastrous voltage dips of the supply. It works with a single trip curve for all loads. Even capacitive loads up to 75,000 F can be handled very easily. The integral fail-safe element (fuse) is adjusted to the circuit breakers rated current and can thus very easily be synchronised with the wired cable cross section. This makes planning much easier.
