Mechanical Locks - Allen-Bradley 140G-R Installation Instructions Manual

Spring Charging Motor 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 spring charging
motor immediately begins to reload the closing springs.
The closing springs can still be charged in the manual mode (using the lever operating mechanism) in a power failure or during maintenance work.
Operating voltage

Insulation voltage:
Spring Charging Motor is always supplied with limit contacts and microswitch for signalling closing springs loaded.
Reference fi gure in the electrical circuit diagrams: M (1)
Auxiliary contacts
The circuit-breaker is supplied with (1) AX1 24 DC gold plated contact and (3) AX2-AX3-AX4 250 AC/DC, microswitch Form C contacts.
The contacts change state based on the opening and closing of the circuit-breaker.

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 have following confi guration: 4 break/make contacts (4 change-over position contacts)
Reference fi gure in the electrical circuit diagrams: AX/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 charging motor.
Reference fi gure 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 Door Interlock (provided on some models)
This device stops the enclosure door from being opened 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 door which fully protects the front of the circuit breaker and allows the IP54 degree of protec-
tion to be obtained. It is assembled on hinges and equipped with a key lock.
