4.3 Electrical diagrams

4.3.1 Wiring code

The power circuits are not shown in the wiring diagrams
for clarity. The control circuit is presented as a typical
circuit diagram and is a combination of numbered basic

diagrams for closing, tripping and indicators.

The number of the complete diagram can be derived by
using the key numbers of the basic plan.

WARNING: Non-standard circuits may be issued for
special orders. Such circuits do not comply with the

diagrams in this instruction. In such a case an appendix is

delivered with the breaker.

These relays are part of internal closing stop circuit.

It is a 24 V DC closed circuit, through all PCBs in the box,
except SEL. Serial connection of all relays is realized

through connections ( :5/:6) in each PCB. This circuit
provides priority of a tripping signal over a closing signal.
Additionally it prevents from closing if the internal supply
24 V DC lost at UVR PCB or NEKO PCB.
