Operation 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. Remote operation is also possible, through the Open and Close coils assembled inside the circuit breaker. The closing coil has an “antipumping” electronic circuit, which prevents successive switching on a single command. Another feature of this product...

Accessories Auxiliary Contacts 1) Indicate circuit breaker status – ON or OFF. 5NO + 5NC Inductive load Alarm Contacts These contacts are incorporated into the protection units and indicate trigger occurrence for any of the protection functions. Configuration Minimum application levels Closing Coil 1) These coils allow remote closing of the circuit breaker through electrical control. This remote control is valid only if the springs of the operating mechanism is charged. Operation voltage “Anti-pumping” characteristic Yes, through electronic circuit Minimum supply time for operation (ms)...

Accessories Motor Operator The motorized drive is used for automatic charging of the circuit breaker springs operating mechanism. The operation begins immediately after curcuit breaker opening and, at the end of this process, an auxiliary contact indicates that the springs are charged. Even if the motorized operation is installed, it is still possible to charge the springs manually through the front lever. Supply Voltage Motor speed (rpm) Charge Time (to spring charging) (s) Charged Spring Auxiliary Contact It has a built-in contacts which transmits the signal to the opening, when motor...

Accessories Protection unit On ABW air circuit breakers, protection against over currents is performed through the ABW-OCR electronic protection units. The ABW-OCR AZ1 is supplied as standard for the circuit breakers from ABW16 up to ABW63 and offers protection against overload (L), timed short circuit (S), instantaneous short circuit (I), ground fault (G) and earth leakage (needs an external CT supplied as optional). These protections may be adjusted through the front dials. Other protection units are supplied as optional accessories, allowing network communication, measurements and other...
