ETAL ESX10-120-DC24V-12AE Selective load protection, electronic trip characteristic Datasheet

Electronic Circuit Protector ESX10
Description
Electronic circuit protector type ESX10 is designed to ensure selective
disconnection of DC 24 V load systems.
DC 24 V 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. As well as an unidentified failure this also means stoppage
of the whole system.
Through selective disconnection the ESX10 responds much faster
to overload or short circuit conditions than the switch-mode power
supply. This is achieved by active current limitation. The ESX10 limits
the highest possible current to values between 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 75,000 µF lamp loads, 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 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.
The ESX10, with a width of only 12.5 mm, can be plugged into the
E-T-A power distribution socket Module 17plus ensuring ease of
installation and saving space in control cabinets.
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 MOSFET and the load circuit may be re-activated
via the remote electronic reset input or manually by means of the
ON/OFF button. When starting up the system, the load circuit may
also be manually disconnected.

(= terminal 13,14 or 12

of Module 17plus)
momentary switch due to the falling edge of
a +24 V pulse.
Caution: unused slots
The reset signal will be fed in terminal 13, 14
have to be fitted with
or 12 of Module 17plus and is internally
jumpers
pre-wired.
The reset simultaneously affects all blocked
ESX10-124/-127 channels of the power
distribution system, all switched on
ESX10-124/-127 channels remain
unaffected. With type ESX10-125 the reset
only affects the device concerned. By
connecting the individual terminals 12 of
the Module 17plus a joint reset signal for
all ESX10-125 may be generated.

Please note:
l The user should ensure that the cable cross sections of the relvant
load circuit are suitable for the current rating of the ESX10 used.
l 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
