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. Failure and

• Electronic current limitation occurs at typically 1.8 x In†
which means that under all overload conditions
