Electronic Circuit Protector ESX10-T.-DC 24 V Description E-T-As ESX10-T electronic circuit protector is only 12.5 mm wide and selectively protects all DC 24 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 24 V switch mode power supplies without tripping fast and 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. Besides fixed current ratings from 0.5 A to 12 A, adjustable current rating versions are also available. The integral fail-safe element (fuse) is adjusted to the circuit protectors rated current and can thus very easily be synchronised with the wired cable cross section. This makes planning much easier.
