Gearmotor for automatic loading of the closing springs (M)
Automatically loads the closing springs of the circuit-breaker's operating mechanism. Once the circuit-breaker has closed, the gearmotor im-
mediately begins to reload the closing springs.
The closing springs can still be loaded in the manual mode (using the relative lever of the operating mechanism) in a power failure or during
maintenance work.
Power supply
24-30 V AC/DC
48-60 V AC/DC
100-130 V AC/DC
220-250 V AC/DC
Operating limits: 85…110% Un (Standard CEI EN 60947-2)
Insulation voltage: 2500 V 50 Hz (for 1 min.)
IT is always supplied with limit contacts and microswitch for signalling closing springs loaded.
Reference figure in the electrical circuit diagrams: M (1)
Mechanical and electrical trip signalling for overcurrent releases
The following signals are available after the overcurrent release has tripped:
a) Mechanical trip signalling for overcurrent releases
Enables visual signalling on the operating mechanism by pushing the trip button in when the circuit-breaker has been opened after the overcurrent
releases have tripped. The circuit-breaker can only be closed again by putting the pushbutton back in its normal position in the standard configuration.
Reference figure in the electrical circuit diagrams: S51 (13).
b) Electrical trip signalling for overcurrent releases
Enables visual signalling on the operating mechanism (mechanical) and remotely (electrically, by means of a change-over switch) of the circuit-
breaker having opened after tripping of the overcurrent releases. The mechanical indicator pushbutton must be reset before the circuit-breaker
can be reset. Reference figure in the electrical circuit diagrams: S51 (13).
Inrush power consumption (Ps): DC = 500 W
AC = 500 VA
Rated power (Pn): DC = 200 W
AC = 200 VA
Inrush time 0.2 s
Loading time: 4-5 s
Auxiliary contacts
Auxiliary contacts installed on the circuit-breaker are available and allow an indication of the circuit-breaker's state to be obtained. A special ver-
sion of the auxiliary contacts is also available (gold plated contacts) for use at less than 24 V rated voltage (digital signals).
The following versions are available:
a) Electrical signalling of circuit-breaker open/closed
ELECTRICAL signalling of the circuit-breaker state (open/closed) can be obtained with 4 auxiliary contacts.
The auxiliary circuits can have following configuration: 4 break/make contacts (4 change-over position contacts)
Reference figure in the electrical circuit diagrams: Q/1 to 4 (22)
b) Contact for signalling closing springs loaded/unloaded
This consists of a microswitch, which allows remote signalling of the state of the closing springs of the circuit-breaker operating mechanism.
The contact is always supplied with the spring loading gearmotor.
Reference figure in the electrical circuit diagrams: S33 M/2 (11)
Sensors for the neutral conductor outside the circuit-breaker
The sensor allows neutral protection to be achieved by means of connection to the overcurrent release and is only available for three-pole circuit-
breakers. It is supplied on request.

10.2 Mechanical locks
Lock in open position
The circuit-breaker can be locked in open position by means of a padlocks up to 3 padlocks (not supplied): Ø 4 mm.
Mechanical lock for compartment door
Supplied as standard, this device stops the compartment door from being operated when the circuit breaker is closed and prevents the circuit
breaker from being closed when compartment door is open.
IP54 door protection
This is provided by means of a transparent plastic escutcheon plate which fully protects the front of the circuit-breaker and allows the IP54 degree
of protection to be obtained. It is assembled on hinges and equipped with a key lock.
