AIR CIRCUIT BREAKERS

CRITICAL CIRCUIT PROTECTION WHEN CURRENT SPIKES

Air circuit breakers protect your electrical circuits from overcurrent and short circuits by tripping to interrupt supply and prevent equipment damage.

About Air Circuit Breakers

One fault can shut down everything

When an ACB detects a current that is greater than expected, it “trips” – the contacts within the ACB separate, creating an arc. The ACB uses air to extinguish this arc, interrupting the circuit and protecting your equipment.

There are several types of ACB commonly in operation, and all require regular maintenance to function correctly. Circuit breakers can exhibit several types of faults, including failure to trip when excess current is present, or tripping unnecessarily when there is no excess.

Potential consequences of not maintaining your ACB include:

Failure to operate when required

Injury to staff or customers

Damage to expensive equipment

Unnecessary business downtime

Fires within switchboards

Each of these consequences can be costly to a commercial building or data centre operator. Regular inspection and maintenance of ACBs can help detect any potential faults and prevent these costly outcomes.

Why you need air circuit breaker maintenance

ACBs protect circuits and equipment from overcurrent and short circuits

Without maintenance, ACBs can fail to trip or nuisance trip, interrupting power

Faulty ACBs can lead to injury risk, equipment damage, downtime, and switchboard fires

The benefits of professional air circuit breaker maintenance

Regular inspection and testing helps detect faults early and prevent costly failures

Improved protection for people, switchboards, and high-value equipment

Reduced unplanned outages through more reliable breaker operation

Testing completed in line with AS 2467-2008
