Contact for electrical signalling circuit-breaker open due tripping the overcurrent release.. Fig. SACE SOR TEST UNIT Test/monitoring Unit (see note R) Fig. Consult this catalogue for information on how make out order. Motor circuit load the closing springs. Circuits the measuring module PR120/V the PR122/P and PR123/P releases connected inside the three-pole circuit-breaker with outside neutral conductor (optional for the release PR122/P)(see note U). Fig. Fig.TI/L3 Current transformer located phase L3 TO Homopolar toroidal current transformer (see note W) Vaux Auxiliary power supply voltage (see note F) UI/L1 Current sensor (Rogowski coil) located phase L1 UI/L2 Current sensor (Rogowski coil) located phase L2 UI/L3 Current sensor (Rogowski coil) located phase L3 UI/N Current sensor (Rogowski coil) located neutral UI/O Current sensor (Rogowski coil) located the conductor connecting earth the star point the MV/LV transformer (see note G) W1 Serial interface with control system (external bus): EIA RS485 interface (see note E) W2 Serial interface with the accessories PR121/P, PR122/P and PR123/P releases (internal bus) X Delivery connector for auxiliary circuits withdrawable version circuit-breaker X1. Second set circuit-breaker auxiliary contacts (not available for PR122/P and PR123/P releases)(see note V) Fig. Third set supplementary auxiliary contacts outside the circuit-breaker. First set circuit-breaker auxiliary contacts. Fig. Fig. Fig. Fig. Fig. Fig. Fig. Circuits the indicator module PR120/K the PR122/P and PR123/P releases connection (optional) (see note ). Fig. Fig. Circuits the measuring module PR120/V the PR122/P and PR123/P releases internallyconnected tothe three-pole and four- pole circuit-breaker (optional for the release PR122/P) (see note U). Fig. Circuits the measuring module PR120/V the PR122/P and PR123/P releases externally connected the circuit-breaker (optional for the release PR122/P) (see note and X). Undervoltage release with electronic time-delay device, outside thecircuit-breaker (see notes and Q) Fig. Circuits the signalling unit PR021/K (outside the circuit-breaker). Contact for electrical signalling springs loaded. Shunt opening release. This may achieved using external circuit comprising permanent make contact, the contact shown in fig. If the same power supply used for the closing and undervoltage releases and the circuit-breaker required close automatically when the auxiliary power supply comes back on, delay must introduced between the undervoltage release accept signal and the energizing the closing release. Second set contacts for electrical signalling circuit-breaker connected,test isolated,disconnected position. Contact for electrical signalling undervoltage release energized(see notes and S). Model L2234 Apparatus Scale L 2778 D 1SDH000461R0002 Page N° 17/25 . Fig. and time-delay relay. Fig. Fig. Fig. Fig. In tib ilitie s The circuits indicated the following figures cannot supplied simultaneously the same circuit-breaker: 6 8 13 14 22 47 43 48 N s A) The circuit-breaker only fitted with the accessories specified the ABB SACE order acknowledgement. The circuit-breaker can only close when the release energized (there mechanical lock closing).. E) For the EIA RS485 serial interface connection see document RH0298 regarding MODBUS communication. Fig. B) The undervoltage release supplied for operation using power supply branched the supply side the circuit-breaker from an independent source. First set contacts for electrical signalling circuit-breaker connected, test isolated, disconnected position. Instantaneous undervoltage release (see notes and Q). Circuit shunt closing release.X7 Connectors for the accessories the circuit-breaker XF Delivery terminal box for the position contacts the withdrawable circuit-breaker (located the fixed part the circuit-breaker) XK1 Connector for power circuits PR121/P, PR122/P and PR123/P releases XK2 XK3 Connectors for auxiliary circuits PR121/P, PR122/P and PR123/P releases XK4 Connector signal open/close XK5 PR120V module connector XO Connector for YO1 release XV Delivery terminal box for the auxiliary circuits the fixed circuit-breaker YC Shunt closing release YO Shunt opening release YO1 Overcurrent shunt opening release (trip coil) YO2 Second shunt opening release (see note Q) YR Coil electrically reset the circuit-breaker YU Undervoltage release (see notes and Q) D rip tio fig s Fig. Fig. Second shunt opening release (see note Q). Circuits the communication module PR120/D-M the PR122/P and PR123/P releases (optional) (see note E). Auxiliary circuits PR122/P and PR123/P releases (see notes and V). Contact for electrical signalling circuit-breaker open due tripping the overcurrent release and electrical reset coil. Circuits the indicator module PR120/K the PR122/P and PR123/P releases connection (optional) (see note V). The circuit- breaker may closed only after pressing the reset pushbutton energizing the coil. Fig. The circuit-breaker may closed only after pressing the reset pushbutton. Auxiliary circuits PR121/P release (see note F)
