Third set supplementary auxiliary contacts outside the circuit-breaker. Fig. Fig. Fig. and time-delay relay. E) For the EIA RS485 serial interface connection see document RH0298 regarding MODBUS communication. 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). Consult this catalogue for information on how make out order. Contact for electrical signalling undervoltage release energized(see notes and S). Fig. Fig. Undervoltage release with electronic time-delay device, outside thecircuit-breaker (see notes and Q) 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. Shunt opening release. 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. B) The undervoltage release supplied for operation using power supply branched the supply side the circuit-breaker from an independent source. Fig. Fig. This may achieved using external circuit comprising permanent make contact, the contact shown in fig. 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). Fig. Circuits the communication module PR120/D-M the PR122/P and PR123/P releases (optional) (see note E). Fig. 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. Fig. Second set circuit-breaker auxiliary contacts (not available for PR122/P and PR123/P releases)(see note V) Fig. Auxiliary circuits PR121/P release (see note F).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. Contact for electrical signalling springs loaded. Circuits the indicator module PR120/K the PR122/P and PR123/P releases connection (optional) (see note V). Auxiliary circuits PR122/P and PR123/P releases (see notes and V).. Fig. The circuit- breaker may closed only after pressing the reset pushbutton energizing the coil. 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. Circuit shunt closing release. Contact for electrical signalling circuit-breaker open due tripping the overcurrent release and electrical reset coil. SACE SOR TEST UNIT Test/monitoring Unit (see note R) Fig. Circuits the signalling unit PR021/K (outside the circuit-breaker). Instantaneous undervoltage release (see notes and Q). Second shunt opening release (see note Q). The circuit-breaker may closed only after pressing the reset pushbutton. Fig. Fig. Fig. Model L2234 Apparatus Scale L 2778 D 1SDH000461R0002 Page N° 17/25 . Circuits the indicator module PR120/K the PR122/P and PR123/P releases connection (optional) (see note ). Second set contacts for electrical signalling circuit-breaker connected,test isolated,disconnected position. Fig.. The circuit-breaker can only close when the release energized (there mechanical lock closing). Fig. Contact for electrical signalling circuit-breaker open due tripping the overcurrent release. First set contacts for electrical signalling circuit-breaker connected, test isolated, disconnected position. Fig. First set circuit-breaker auxiliary contacts. Motor circuit load the closing springs
