A Leakage Current Relay is a critical safety device used in electrical systems to detect and protect against leakage currents that could pose serious risks to both equipment and personnel. As the use of electricity becomes increasingly widespread in residential, commercial, and industrial sectors, the importance of safeguarding electrical circuits against leakage current has never been more crucial. Leakage current is the unintended flow of current through non-intended paths, often due to faulty insulation or grounding issues. When left unchecked, leakage currents can lead to electrical shock hazards, fire risks, and even equipment failure. This is where a Leakage Current Relay plays an essential role in providing proactive protection.
