Power distribution system SVS14
Description
The power distribution system SVS14-10 optimises DC 24 V distribution
on the field level in automated process control, industrial production
and chemical plants. The system holds an integral ammeter (display
25 A) for the total current and offers ten ways for electronic and
thermal-magnetic circuit breakers including group signalling. It allows
protection of transformers, actuators, solenoids, peripheral PLCs,
intelligent terminals etc. on the field level. Particularly for systems with
a great number of sensors/actuators the SVS14 power distribution
system enables a space-saving and cost-effective design of protection
control cabinets.
Any load circuit which might be disconnected due to overload or short
circuit generates a single signal which will be summarised in a group
signal directly on the power distribution system and which will be fed
back directly to control.
SVS14-10-C22-A01
The SVS14 is a track-mountable system and accommodates 10 electronic
or thermal-magnetic circuit breakers. All terminals (entry line DC +24 V,
GND (-) for self-supply, load outputs L(+) and group signalling are
standard screw terminals.
Technical data (T_amb = 25 °C, U_B = DC 24 V)
The SVS14 accommodates the following E-T-A types:
Electronic circuit breaker
ESS20-003..
Electronic circuit protector
ESX10-103..
Thermal-magnetic circuit breaker
2210-S211, 3600-P10,

Application
Modular power distribution system for current limited DC 24 V -
applications. In the event of current supply rated higher than 25 A
and with battery-buffered supplies please use a 25 A protection
with medium delay trip curve (e.g. E-T-A type 4220-T, 2210-T).
