ESX10-T
selected in fixed values from 0.5 A...12 A. Failure and
status indication are provided by a multicolour 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 and reset of individual load circuits.
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 or manually by means of the
ON/OFF button.

Zone 2
Electronic circuit protection type ESX10-T is designed to
ensure selective disconnection of 24VDC load systems.
24VDC 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-T responds
much faster to overload or short circuit conditions than
the switch-mode power supply. This is achieved by
active current limitation. The ESX10-T 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-T can be

Attention: when mounted side-by-side without convection the ESX10-T should not carry more
than 80% of its rated load with 100% ON duty due to thermal effects.
Please note:
• The user should ensure that the cable cross sections of the relevant load circuit
are suitable for the current rating of the ESX10-T used.
• Automatic start-up of machinery after shut down must be prevented (Machinery
Directive 98/37/EG and EN 60204-1). In the event of a short circuit or overload
the load circuit will be disconnected electronically by the ESX10-T.
• Refer to UL/CSA file for proper wiring and installation techniques.
