ESS31-TC-001-DC24V-6A
Elektronický dvoupólový jistič s nadproudovou ochranou a fyzickým izolačním oddělením pro průmyslové aplikace
The model ESS31-T extends our product group of electronic overcurrent protection devices for DC 24 V applications. At a width
of only 12.5 mm it provides selective protection for all DC 24 V load circuits. This is achieved by a combination of active electronic
current limitation in the event of a short circuit and overload disconnection at typically 1.2 times rated current. The ESS31-T
is track-mountable and provides ease of installation for groups of devices with several circuits. DC 24 V switch-mode power supplies
are widely used in automation today. In the event of an overload, however, they turn down the output voltage which is intended
to power all connected loads. So if there is a failure in a single load of the system, the supply voltage will break down also in all other
load circuits. Not only does this frequently cause undefined fault conditions, but it can even lead to machine stoppages or system
downtimes.
