Power Distribution System SV Description The power distribution system SV for rail mounting distributes the current supplied by a DC V switchmode power supply to channels and selectively protects the connected loads by means of the inserted circuit breakers. With a max. load current of A per channel and a max. total current of 0 A the SV provides ease of wiring in shortcircuit limited DC V applications. Eight protected + load outputs per channel and minus terminals help to reduce wiring time significantly. Suitable for the following circuit breaker types: Electronic circuit breaker ES00.. Electronic circuit protector ESX00.. Features and benefits l Systematic integration of protection and distribution functions l Power distribution and selective protection of DC V load circuits allinone l Clear distribution and wiring concept l Significant reduction of wiring time l Ease of planning, design and installation l Ease of maintenance, diagnostics and system extension l Compact power distribution for compact control cabinets l Additional integral minus terminals l External loopin facilities between load output terminal () and () per channel l Signal contact can be arranged in groups: F F = gr., F F = gr. possible Ordering information Type SV Power distribution system for ES00, ESX00 l For shortcircuit limited DC V applications l Max. 0 A continuous load l One integral circuit breaker (CB): overcurrent protection for splitgroup and group signalling, ED flashing red after trip of CB l Including insulated wire bridges Y 0 0 between and fitted l Including insulated wire bridge Y 0 0 l Accessories: jumpers SBP0A (for free channels), order separately Version, max. number of circuit breakers on the system 0 circuit breakers (F...F) Fitting variant, load output / minus and signalling terminals B0 Standard: completely fitted with plugin type screwless terminals (max.,mm, without wire end ferrule) Minus terminals K0 minus terminals Special version SB0 with marked terminals supply terminals +/+/+/// load output terminals ////////// minus / signal terminals //// SV 0 B0K0SB0 ordering example Accessories: jumper and wire bridge see page Accessories Technical data (T amb = C, U B = DC V) Application Modular power distribution system for short circuit limited DC V applications Supply Voltage rating DC V (...

In the event of a failure (short circuit/overload) the load circuit will be disconnected by the circuit breaker. l After tripping of the circuit breaker and before reset the cause of tripping (short circuit or overload) must be remedied. l The international standards (e. g. DIN VDE 000 for Germany) must be observed with respect to installation and selection of cables. Mounting position www.eta.de
