Datasheet Electronic Circuit Protection ESX10-TC 12VDC status indication are provided by a multicolor LED and an integral short-circuit-proof status output or a relay signal contact. Remote operation is possible by means of a remote reset signal or a remote ON/OFF control signal. The manual ON/OFF button allows separate actuation of individual load circuits. The ESX10-TC, with a width of only 12.5 mm, can be snapped onto symmetrical rails for easy installation and control cabinet space savings. Upon detection of overload or short circuit in the load circuit, the MOSFET of the load output will be blocked to interrupt the current flow. The load circuit can be re-activated via the remote electronic reset input, control input ormanually bymeans of the ON/OFF button. Zone 2 Electronic circuit protection type ESX10-TC is designed to ensure selective disconnection of 12VDC load systems. 12VDC power supplies, which are widely used in industry today, will shut down the output in the event of an overload with the result that one faulty load in the system can lead to complete disconnection of all loads. Through selective disconnection the ESX10-TC responds much faster to overload or short circuit conditions than the switch-mode power supply. This is achieved by active current limitation. The ESX10-TC limits the highest possible current to 1.3 to 1.8 times the selected rated current of the circuit protector. Thus it is possible to switch on capacitive loads of up to 20,000 μF, but they are disconnected only in the event of an overload or short circuit. For optimal alignment with the characteristics of the application the current rating of the ESX10-TC can be selected in fixed values from 1.0 A...10 A.
