The Fuji Electric Co., Ltd. SG53B Earth Leakage Breaker is a protective electrical device that detects leakage current to earth and interrupts power to prevent shock and equipment damage. The SG53B model provides residual-current protection by continuously monitoring the current balance between live and neutral conductors and tripping the circuit when leakage is detected. Use in electrical distribution systems or panels to enhance safety and safeguard connected equipment where earth leakage protection is required.
