PR314/ Electronic Circuit Protector ESX10-TC in 12 V-version
Electronic Circuit Protector also for battery—buffered applications in solar
technology and automation
Product group of electronic circuit protectors ESX10-T now
available for DC12V
Altdorf, 16.11.2009 – E-T-A Elektrotechnische Apparate GmbH,
located in Altdorf, Germany, specialist for protection, switching
and power management, have extended their product range by
the electronic circuit protector ESX10-TC for DC 12 V applications.
It is a track-mountable unit which allows optimum protection also
in combination with DC 12 V switch-mode power supplies and
battery systems.
The space-saving device has a width of only 12.5 mm and 80 mm
each in height and depth. Its low power consumption makes it
ideally suited to battery-buffered DC 12 V applications, for
instance in solar technology. The ESX10-TC is also a very good
choice for applications in factory automation and test equipment in
car manufacturing because it allows realising a consistent DC 12
V voltage platform from the test equipment to the actual motor
control units. In addition the new circuit protector features
switchable load outputs, significantly minimising contact wear
when switching on and off.
The ESX10-TC is track-mountable, either individually or in groups
mounted side-by-side. It offers a sophisticated busbar concept for

line feed and zero potential. The rail terminal side of the housing
has two small plastic slides which can be removed if required and
can be slid into the matching slot on the side to close off the
busbars. This reliably prevents mutual contact of different plus
potentials.
The DC 12 V line entry as well as the load connection to protected
plus and neutral are via screw terminals up to 10 mm² directly on
the devices. The screw terminal is made of a high-strength copper
alloy and has been designed in accordance with the patented
Reakdyn principle. It ensures reliable and safe cable connection.
Reliable selective load protection
The selective load protection with fixed current ratings from 1 A to
10 A ensures exclusive disconnection of the faulty path in the
event of an overload or short circuit in the load circuit without
repercussions on the DC 12 V power supply. Thus it is prevented
that a failure in a single load circuit causes a voltage dip which
would have all loads connected to the switch-mode power supply
fail and which – as a worst case scenario – might lead to a total
system standstill.
Type ESX10-TC limits the short circuit current to 1.3 to 1.8 times
rated current and disconnects the faulty circuit after 100 ms.
Inrush peaks, however, are tolerated – capacitive loads of more
than 20,000 F can be switched. In the event of an overload the
circuit protector disconnects already at 1.1 times rated current
after 3 seconds and signals the failure to the control unit via an
integral control output.
