special version the auxiliary contacts also available (gold plated contacts) for rated voltage under (digital signal). reset the circuit-breaker, necessary reset the mechanical indicator pushbutton. Only available for circuit-breakers withdrawable versions for installing the fixed part. 26/158 .llin s The following signals are available following tripping the overcurrent release: a) echanical trip signalling for overcurrent releases This enables visual signalling the operating mechanism pushing the trip pushbutton when the circuit-breaker has been opened following tripping overcurrent release. Reference figure the electrical circuit diagrams: S51 (13). The basic configuration described above can modified the user indicate normally open normally closed repositioning the faston connector the microswitch. Reference figure the electrical circuit diagrams: S75I (31-32) S75T (31-32) S75E (31-32) c llin rin loaded This consists microswitch which allows remote signalling the state the circuit-breaker operating mechanism closing springs.3 250 0. When contacts for PR122/ PR123 are required, zone selectivity and the PR120/K module are not available. Reference figure the electrical circuit diagrams: S33 M/2 (11) d) ontact for signalling undervoltage release energized (C. The contact is always supplied with the spring loading geared motor. c) Coil for resetting the echanical release trip indicator This enables visual signalling the operating mechanism (mechanical) and remotely (electrically means changeover switch) the circuit- breaker being opened following trip the overcurrent releases. the electrical circuit diagrams: /1^10 (21-22) b) Electrical signalling for circuit-breaker connected/test isolated/disconnected In addition mechanical signalling the position the circuit-breaker, possible have electrical signalling means auxiliary contacts which are installed the fixed part. Power supply: 24-30 AC/DC 220-240 AC/DC__________ _____________________________________110-130 AC/DC__________ Reference figure the electrical circuit diagrams: S51 (14) A ilia ts Auxiliary contacts installed the circuit-breaker are available enable indication the circuit-breaker's status.15 ms The versions available are: a) Electrical signalling for circuit-breaker open/closed It possible have electrical signalling the circuit-breaker status (open/closed) auxiliary contacts. With this accessory, you can reset the mechanical indicator with electronic relay using remote control and this enables the circuit-breaker reset. Reference Fig.aux YU) The undervoltage releases can fitted with contact (by choise, normally closed open) for signalling undervoltage energized for remote signalling the state the undervoltage release.

The auxiliary contacts can have the following configurations: - contacts; group consisting connected signalling contacts, disconnected signalling contacts and test position signalling contact (main contacts isolated, but sliding contacts connected) - contacts; group consisting connected signalling contacts, disconnected signalling contacts and test position signalling contacts (main contacts isolated, but sliding contacts connected). The auxiliary contacts can have the following configurations: - break/make contacts for PR121 normally open normally closed) - break/make contacts for PR122/ PR123 normally open normally closed for the release) - break/make contacts for PR121 normally open normally closed); - break/make contacts for PR122/ PR123 normally open normally closed for the release) - supplementary break/make contacts which can mounted outside the circuit-breaker. b) lectrical and echanical trip signalling for overcurrent releases This enables visual signalling the operating mechanism (mechanical) and remotely (electrically means changeover switch) the circuit- breaker being opened following trip the overcurrent releases. The circuit-breaker can only closed again putting the pushbutton back into its normal position included in the standard configuration. Un max max ç 125 0.
