1. ആമുഖം
The EARU EAL-18 Residual Current Circuit Breaker (RCCB) is designed to provide essential leakage protection in electrical circuits. This device is suitable for AC 50Hz systems with rated voltages of 2P 230V or 4P 400V and rated currents ranging from 1A to 63A. Its primary function is to quickly disconnect the power supply in the event of an electric shock or when the grid leakage current exceeds a specified safe value, thereby protecting both personnel and electrical equipment. The EAL-18 is a Type AC RCCB, specifically engineered to detect and respond to power frequency sinusoidal leakage currents, including those that are suddenly applied or slowly rising. It also supports infrequent switching and starting functions for the line. This product complies with the IEC/EN61008-1 standard.
