Air Circuit Breaker ABW6
Operating System
ABW air circuit breakers operate through a spring system, which can be manually charged through a front lever, or electrically through a motor (supplied as an accessory).
With the springs charged, situation in which the charge indicador shows “CHARGED”, the circuit breaker can be operated locally using the On and Off buttons.
OFF BUTTON
ON / OFFINDICATOR
SPRING CHARGE INDICATOR
CHARGE LEVERON BUTTON
In relation to the installation version, the circuit breakers can be installed as fixed or as withdrawable. The withdrawable version is indicated for applications where eventual replacement or maintenance must be done in the shortest time possible.These curcuit breakers can be positioned at three distinct points in the withdrawable rack:
Inserted: in this position both the power and control circuits are connected. The position indicator shows “CONNECTED”.
Test: position in which the control circuits are connected. The indicator shows “TEST”.
Withdrawn: both circuits are disconnected. The indicator shows “DISCONNECTED”.
Position Indicator
Remote operation is also possible through the closing and opening coils installed inside the circuit breaker. The closing coil is equipped with an “anti-pumping” electronic circuit, which prevents successive re-connections in a single command.
Another feature of the circuit breaker is the indicator on the front showing the status of the product: ON or OFF.
