Air Circuit Breaker (ACB) Testing, Inspection & Maintenance
Air Circuit Breakers (ACBs) are critical components in low-voltage electrical distribution systems, providing protection against overcurrent, short circuits, and electrical faults. These breakers are commonly installed in Main Distribution Boards (MDBs) and act as the primary isolation device during system failures. Regular ACB testing, inspection, and preventive maintenance are essential to ensure reliable performance, prevent unexpected power failures, and maintain electrical safety. At KNX Automation, we deliver professional ACB maintenance and repair services following industry standards to improve system reliability, reduce nuisance tripping, and extend the lifespan of electrical equipment.
