These values refer to apparatus in the withdrawable version in unsegregated switchgear with degree of protection up to IP31 and the following dimensions: 2300x800x900 (HxWxD) for E1-E2-E3. the use of vertical rear terminals is recommended. Fig. The many different possible for ms of switchgear and the conditions which can affect the behaviour of the apparatus always require the solutions used to be verified. Some examples of possible constructions in relation to the shape and size of the circuit-breaker terminals are given in this paragraph. 2300x1400x1500 (HxWxD) for E4-E6. Different capacities for the connections can be made by working on the thickness and on the number of busbars in parallel.1. The various types of terminals are of constant dimensions per size of circuit-breaker: it is normally advisable to exploit the whole contact surface of the terminal. the table shows the continuous current-carrying capacity values of the circuit-breakers installed in switchgear with the dimensions indicated below. Their sizing must be carefully studied by the switchgear designer. N° Emax RH0287002 Scale Pag. The exact shape of the terminals is given in the “Over all dimensions” chapter.

H) In the case of PR113/P or PR113/PD releases mounted on a three-pole circuit-breaker without connection to the neutral outside. In the case where there is the same power supply for the shunt closing releases and undervoltage releases and automatic circuit-breaker closing is required. PR112/P. The shield must be earthed on the circuit-breaker side and on the current transformer side. the connections to the zone selectivity inputs and outputs must be made using a shielded and corded two-pole not longer than 300m. Instructions to follow for replacement of the PR111. G) Protection against earth fault is available with the PR112/P. P) With PR112/PD and PR113/PD releases. PR113/P or PR113/PD releases: – Take special notice of the notes indicated on the electrical circuit diagrams provided – The contact for electrical signalling of undervoltage release energized (Fig. IEC 60364-41 and CEI 64-8. Model L0849 Apparatus Doc. B) The undervoltage release is provided for power supply branched on the supply side of the circuit-breaker or from an independent source: circuitbreaker closing is only allowed with the trip energized (the lock on closing is made mechanically). M) Connect one of the S75I contacts indicated in fig. Dur ing closing of the power supply contact to YO (short-circuit of terminals 4 and 5). N° Emax RH0287002 Scale Pag. For this reason: . N) With PR112/P. it is necessary to short-circuit the terminals of the TI/N transformer. connect the XV-K14 terminal directly to the XV-K16 terminal (contact S75I does not exist). PR112/PD. T o make out the order. PR113/P and PR113/PD releases . the TEST FAILED and ALARM signals will be activated. 31 or 51 in the way shown in figs. PR112/PD. 11. R) The oper ation of the SACE SOR TEST UNIT system + shunt opening release (YO) is guaranteed starting from 75% of the Uaux of the shunt opening release. Q) The second shunt opening release must be installed as an alternative to the undervoltage trip. N° 18/24 . The coils can be controlled directly from the K51/YO and K51/YC contacts with maximum voltage values of 60VDC and 240-250VAC for PR112/PD. the TEST FAILED signal may be activated at the same moment.5 mA]. 12 of the enclosed diagrams) must be removed from the terminal box.Notes A) The circuit-breaker is only fitted with the applications specified in the ABB order confirmation. the contact indicated in figure 12 and a time-delay relay.In the case of an opening coil supplied continuously. 21 in the way shown in fig. PR113/P and PR113/PD releases b y means of a current transformer located on the conductor which connects the MV/LV transformer star centre to earth. it is necessary to introduce a delay of 30 milliseconds between the instant of consent of the undervoltage release and energisation of the shunt closing release.If the control of the opening coil is carr ied out impulsively. The shield must be earthed on both sides (sensor and circuit-breaker). when the circuit-breaker is to be removed. 42-44. the SACE SOR TEST UNIT is not able to determine the state of the opening coil. refer to the corresponding user manuals. . L) The contact cannot be used if the PR113/P or PR113/PD unit is present. the TEST FAILED signal should only be considered an actual alar m signal if it remains for longer than 20s. In this case. must be made using a shielded and corded two-pole cable (see instruction manual) not longer than 15 m. PR112/PD. on return of the auxiliary voltage.RH0297 for LON communication . In the case of fixed version circuit-breakers. I) The contact cannot be used if the PR112/PD and PR113/PD unit is present. 240-250VDC and 240-250VAC for PR113/PD. For other installation configurations. Having requested a Vaux insulated from earth. 15. please see par. C) In the case of a fixed version circuit-breaker with current transformer on the neutral conductor outside the circuit-breaker. The shield must be earthed on the selectivity input side. the T3 and T4 poles of the X (or XV) connector must be short-circuited (by the customer). S) Also available in the normally closed contact version. This can be carried out by means of a circuit outside the circuit-breaker including a per manent closing contact. the power supply of the YO and YC coils must not be branched from the main one. PR113/P and PR113/PD releases. allows actuation of all operations of the PR112/P. one of the closing contacts and one of the opening contacts of the circuit-breaker indicated in fig. the connection between the voltage sensors (TV) and the circuit-breaker must be made using a shielded and corded two-pole cable not longer than 15 m.

T) Configuration valid for four-pole or three-pole circuit-breaker with external neutral. The connection between terminals 1 and 2 of the TI/O current transformer and the T5 and T6 poles of the X (or XV) connector. one must use “galvanically separated converters” in compliance with IEC 60950 (UL 1950) or equivalent standards that ensure a common mode current or leakage current [(see IEC 478/1 CEI 22/3) not greater than 3.
