YS Engineering Solutions offers thorough ACB (Air Circuit Breaker) Testing and Service to ensure these critical safety devices operate correctly. The process involves a combination of visual inspections, mechanical checks, and advanced Electrical Testing. Their skilled technicians meticulously clean and lubricate components, inspect for wear and tear, and verify the physical condition of the contacts and arc chutes. The most crucial part of their service is the secondary injection testing, which uses specialized equipment to simulate fault currents and confirm that the electronic trip unit functions within the correct parameters. This comprehensive approach ensures that the ACB will perform as designed during an actual electrical fault, protecting both equipment and personnel from serious damage. The company also offers annual maintenance contracts (AMCs) for ongoing, proactive care.
