ACB (Air Circuit Breaker) maintenance and service are vital for ensuring safe and efficient operation of electrical systems. Regular maintenance includes inspection, cleaning, lubrication of moving parts, tightening of connections, and testing of protective trip units. Over time, ACBs can experience wear and tear, dust accumulation, or contact degradation, which may lead to malfunction or failure. Preventive servicing helps detect issues early, reduces downtime, and extends the lifespan of the breaker. It also ensures compliance with industry safety standards. ACB maintenance is especially important in industrial and commercial settings, where uninterrupted power is critical for operations and equipment protection.
