Electronic Circuit Protector ESX10-T.-DC 24 V
Description
E-T-A’s 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 μF 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 protector’s rated current and can thus very
easily be synchronised with the wired cable cross section. This makes
planning much easier.
