14. Circuit diagrams

WARNING:
Before installing the circuit-breaker, carefully read notes F and O on the circuit diagrams.
Operating status shown
The circuit diagram is for the following conditions:
- withdrawable circuit-breaker, open and racked-in
- circuits de-energised
- releases not tripped
- motor operating mechanism with springs unloaded.
Versions
The diagram shows a circuit-breaker in withdrawable version; it can be applied to a fi xed version circuit-breaker as well.
Fixed version
The control circuits are fi tted between terminals XV (connector X is not supplied).
With this version, the applications indicated in fi gures 31 and 32 cannot be provided.
Withdrawable version
The control circuits are fi tted between the poles of connector X (terminal box XV is not supplied).
Version without overcurrent release
With this version, the applications indicated in fi gures 13, 14, 41, 42, 43, 44, 45, 46, 47, 48, 62 cannot be provided.
Version with PR121/P electronic release
With this version, the applications indicated in fi gures 42, 43, 44, 45, 46, 47, 48 cannot be provided.
Version with PR122/P electronic release
With this version, the applications indicated in fi gure 41 cannot be provided.
Version with PR123/P electronic release
With this version, the applications indicated in fi gure 41 cannot be provided.
