1. Description

1.1 General characteristics

140G-R circuit-breakers and disconnectors consist of a plastic structure which houses the operating mechanism, the poles and the auxiliary parts. Each pole is insulated from the others and contains the circuit breaking parts and the current sensor of the corresponding phase. The ﬁxed version circuit-breaker has its own terminals for connection to the power circuit.

2. Checking on receipt

Examine the condition of the material received and make sure that it corresponds to what was ordered. Any damage or non-compliance found when the material has been unpacked, which must be carried out with due care, must be notiﬁed within 5 days of receipt and the number of the shipping notice must be indicated on the notiﬁcation.

3. Storage, lifting and weights

Protected by an external wooden crate, the circuit-breaker is fastened with screws to the pallet used for transport or to the bottom of the packing crate. If the circuit-breaker must be stored for even a short period of time before being put into service, after having been checked on receipt it must be its back into its container and covered with a waterproof tarpaulin.

Caution

– Store the circuit-breaker in a dry, dust-free room well away from aggressive chemicals. – Place the circuit-breaker and any ﬁxed part on a horizontal surface, not in direct contact with the ﬂoor but on a suitable support (Fig. 4). – The maximum number of circuit-breakers that can be stacked on top of each other is shown in ﬁgure 5. – Keep the circuit-breaker in the open position with the closing springs unloaded to prevent unwarranted stress and the risk of accidents to the

personnel.

Comply with the following instructions when lifting the circuit-breaker: the circuit-breakers must be placed on a sturdy surface and preferably lifted with an appropriate fork-lift truck. The use of ropes is, however, permitted: In this case, the lifting ropes ust be attached as shown in the ﬁgure.

Note

The weights given in the table refer to circuit-breakers complete with LSIG releases and relative current sensors, excluding the accessories.

4. Installation

4.1 Installation conditions

Install the circuit-breaker in a dry, dust-free, non-corrosive place where it will not be subjected to shocks or vibrations. When this is not possible, assemble it inside a switchboard with a suitable degree of protection. For preparation of the installation ambient, refer to the “Overall dimensions” chapter, which provides information about the following points:

– minimum installation volumes of the circuit-breakers and derived

versions – clearances to be respected for circuit-breakers in compartments – overall dimensions of the circuit-breakers – drilling holes for ﬁxing purposes – drilling holes in the compartment door

The operations required for installation, putting into service, routine and supplementary maintenance must be performed by skilled personnel with detailed knowledge of the equipment.

To install a circuit-breaker in the switchboard, just ﬁx it to a vertical surface with M8 screws. (ﬁg. 7 )

The circuit-breaker must only be installed in a vertical position.

4.2 Installation of the ﬂange on the compartment door (Fig. 8)

– Drill the holes in the compartment door indicated in the section entitled “Overall dimensions”. – Apply the ﬂange (1) to the front of the compartment door and ﬁx it from the inside with the self-tapping screws (2).

5.1.2. Examples of connection busbar layouts depending on the types of terminals

The busbars allow connections to be made between the terminals of the circuit-breaker and the busbars of the switchboard. They must be accurately sized by the switchboard design engineer. This section illustrates examples of possible constructions, depending on the shape and size of the circuit-breaker terminals. It is normally advisable to use the entire contact surface of the terminal, thus the width of the busbar should be the same as that of the terminal. Different capacities can be obtained for the connections by adjusting the thickness and number of busbars in parallel. In certain cases, reductions in the width of the connection in relation to that of the terminal can be allowed, as shown in the examples below.

5.2.3 Assembly procedures for the connection busbars

Check the state of the contact surfaces of the connections very carefully: they must be very clean and free from burrs, dents and traces of rust

- which must be removed with a ﬁne ﬁle or emery cloth to prevent localized increases in temperature. On completion of the operation, remove any traces of grease or dust with a cloth soaked in a suitable solvent. When aluminium connections are used, the contact surfaces must be tin-plated. Make sure that the connections are unable to exert any strain on the terminals in any direction. Always insert a ﬂat washer with a large diameter (to distribute the tightening pressure over the widest possible area) and a spring washer. Establish contact between the connection and terminal and fully tighten the ﬁxing screws. Always use two wrenches (to prevent the insulating parts from being unduly stressed) and apply the tightening torque of the main terminals = 70 Nm/615 lb in for M12 high-strength screws. Check tightness after 24 hours.

5.2 Wiring of the auxiliary circuits of the circuit-breaker

There is a special terminal board ﬁtted with screw terminals for connecting the auxiliary circuits. The terminals are marked with alphanumerical identiﬁcation codes as indicated in the electrical circuit diagram. The terminal board is accessed immediately when the compartment door is opened.

Note

On request, a transparent cover that increases the degree of protection to IP54 can be installed on the front of the circuit-breaker. The cover is equipped with a key lock.

7.2 Circuit-breaker closing and opening procedures

Circuit-breaker operation can be either manual or electrical.

a) Manual operation for loading the closing springs

– Make sure that “O” (circuit-breaker open) is displayed by the indicator – Make sure that the indicator (6) is WHITE (springs unloaded) – Repeatedly operate the lever (2) until the colour of the indicator (6)

changes to YELLOW

b) Electrical operation for loading the closing springs

Electrica operation of the circuit-breaker is possible when the following accessories are present (supplied to order): – gearmotor for automatic loading of the closing springs – shunt closing release – shunt opening release. The gearmotor automatically reloads the springs after each closing operation until the yellow indicator appears (6, Fig. 15). If there is a power failure during the loading operation, the gearmotor stops and automatically continues with the spring loading operation once the power returns. However, it is always possible to complete the reloading operation in the manual mode.

Fig. 15

DIR 1000682R0002 (L5757)

(8)

c) Circuit-breaker closing

This operation can only be carried out when the closing springs are fully loaded. Press the push-button (5) marked with the letter “I” for closing in the manual mode. When there is a shunt closing release, the operation can also be carried out in the remote mode by means of the special control circuit. Closing is signalled by the relative indicator (3), which moves to the “I” position. Moreover, the indicator of the state of the springs (6) moves to the WHITE position. The control has enough energy for the opening operation even when the closing springs are unloaded. If present, the gearmotor immediately begins the automatic spring loading operation.

Fig. 16

d) Circuit-breaker opening

Press the push-button “O” (1) to open the circuit-breaker in the manual mode. When there is a shunt opening release, the operation can also be carried out in the remote mode by means of the special control circuit. The open state is signalled by the appearance of the letter “O” in the indicator (3).
