ACB REPAIRING SERVICES
Air Circuit Breaker (ACB) Maintenance
We advise a suitable maintenance schedule to guarantee your equipment operates dependably. We visit sites for routine maintenance as well as in case of emergencies when an ACB is not operating properly.
Each site and ACB are unique. This indicates that a service schedule will be evaluated following a meeting or visit with you. The schedule is based on the environment the ACBs operate in and how frequently they operate; insufficient use necessitates maintenance just as much as excessive use does.
With the help of our service plan, we can repair or remove your breakers as needed and work on them on-site. Some components of the ACB are disassembled during the service to allow for inspection, lubrication, repair, and testing. We can test the functionality of the ACBs electronic trip units and their parameters thanks to a variety of specialised secondary injection test equipment.
Distribution & Control Panel Maintenance
Additionally, we provide a free service for your distribution and control panels. We advise cleaning the panels’ interior and exterior on a regular basis to get rid of dust and dirt. The supply and distribution busbar connections can be re-torqued at the same time as the switchgear connections can be checked and tightened. We have observed numerous instances where system failure due to lack of maintenance can result in noise, excessive heat, and loose connections on busbars.

The supply and distribution busbar connections can be re-torqued at the same time as the switchgear connections can be checked and tightened. We have observed numerous instances where system failure due to lack of maintenance can result in noise, excessive heat, and loose connections on busbars.
Common mistakes we observe:
(Turn “OFF”) Air Circuit Breaker won’t open
(Turn “ON”) Air Circuit Breaker won’t close
Inability to recharge or reset an air circuit breaker
Air Circuit Breaker will not trip as intended or necessary.
When turned on, the air circuit breaker will not stay closed.
Tripping off of the air circuit breaker in a random or bothersome manner
The majority of these common faults can be prevented with the right maintenance schedule.
