YS Engineering Solution offers comprehensive Air Circuit Breaker (ACB) Maintenance and Service, a vital process for ensuring the safety and reliable operation of the main incoming power protection in low-voltage systems. The service is meticulous, beginning with a detailed mechanical and Electrical inspection. Key Maintenance steps include thorough cleaning of the contacts, operating mechanism, and arc chutes to remove conductive dust. They perform contact resistance measurement to check for excessive wear and minimize heat generation. Crucially, the service involves lubrication of moving parts and testing/calibration of the trip unit (using secondary injection) to verify that the ACB will correctly interrupt fault currents. This expert Maintenance regimen significantly extends the breaker's lifespan and prevents catastrophic failures in the Electrical network.
