ACB (Air Circuit Breaker) Repair and Maintenance are critical services for ensuring the safety and reliability of high-current electrical systems. Maintenance is a proactive process that includes a thorough visual inspection, cleaning of the breaker and its components, and checking for any signs of wear, overheating, or loose connections. A key part of the process is the functional testing, which involves checking the tripping mechanism, auxiliary contacts, and insulation resistance. Repairs, on the other hand, are performed to address specific failures, such as a faulty trip unit, worn-out contacts, or mechanical issues. Companies like Universal Electrical Services in Gurugram specialize in these services, using calibrated testing equipment to diagnose problems and genuine spare parts for replacements, ensuring the ACB is restored to its original operating condition and continues to provide essential protection for the electrical system.
