Electronic Circuit Protector ESX10-TA/-TB-DC 24 V
Warning
This device is only suitable for operation at 24 VDC (safety
extra-low voltage). Direct connection of this device to a 110 V,
230 V or 400 V power system, or to power systems with a higher
voltage, may consequently result in death, severe personal injury
or substantial property damage. Only qualified personnel should
work on or around this equipment. The product will function
correctly and safely only if it is transported, stored, set up and
installed as intended.
Caution
Electrostatic sensitive devices (ESD) – the device must be opened
only by the manufacturer.
Disposal guideline
Packaging and packing aids can be recycled and should always
be returned to use.
Note
More detailed information can be obtained from local E-T-A subsidiaries
or from the homepage www.e-t-a.de. The product is subject to techni-
cal modifications. In case of doubt the German text takes precedence.
If used under Ex conditions, this device must only be actuated of the
immediate environment is verifiably not classified as a hazardous area.
Automatic start-up of machinery after shut down must be prevented (Ma-
chinery Directive 2006/42/EG and EN 60204-1). In the event of a short
circuit or overload the load circuit will be disconnected electronically by
the ESX10-TA-/TB.
Installation instructions
The type ESX10-TA-/TB can be snapped onto symmetrical rail EN 60715.
Please observe the marking of the ESX10-T signal inputs and outputs,
connection diagrams etc. Before power up the cables have to marked
so as to prevent reverse polarity. The user should ensure that the cable
cross sections of the relevant load circuit are suitable for the current ra-
ting of the ESX10-T used. In the event of Ex applications it has to be
ensured that protection class IP 54 is achieved after installation in a UV-
protected, fully enclosed room / control cabinet. IEC/EN60079-0 and IEC/
EN 60079-14 have be observed for installation.
Safety
This device is not protected against reversed polarity of the input
voltage. It has to be protected against overvoltage > 32 V.
Danger of explosion: Incorrect connection of cables can cause
ignition. The output and the device are protected by an internal,
non-exchangeable blade fuse. Use in aggressive mixed media was
not tested. When mounted side-by-side without convection, the
devices should not carry more than 80 % of its rated load with
100 % ON duty due to thermal effects.

1 Description
Electronic circuit protector type ESX10-T is designed to ensure
selective disconnection of DC 24 V load systems because it 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 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 potential-free 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.
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.

lThe trip time is typically 3 s in the range between 1.1 and 1.8 x IN
(e.g. ESX10-TB-...-6 A)
lElectronic current limitation ILimit occurs at typically 1.8 x IN
which means that under all overload conditions (independent
of the power supply and the resistance of the load circuit)
the max. overload before disconnection will not exceed 1.8
x INtimes the current rating. The individual current limitation
value ILimit depends on the current rating (see table1). Trip
time is between 100 ms and 3 sec (depending on overload
or at short circuit).
lWithout this current limitation a considerably higher overload
current would flow in the event of an overload or short circuit.
