The DZ47TRLE series transparent miniature residual current circuit breaker (RCBO) is an integrated protection device designed for low-voltage terminal distribution systems. It combines miniature circuit breaker functions with residual current protection, providing comprehensive protection against overload, short circuit and earth leakage faults. The product is suitable for AC 50Hz systems with rated voltage of 230V/400V and rated current ranging from 6A to 60A. It provides reliable protection for electrical lines, equipment and users by quickly disconnecting the circuit under abnormal conditions. The transparent housing design allows users to directly observe the internal contact status and operating condition of the circuit breaker, making inspection, maintenance and troubleshooting more convenient. The DZ47TRLE series supports multiple pole configurations, including 1P+N, 2P, 3P, 3P+N and 4P, meeting different requirements for single-phase and three-phase terminal distribution systems. The product supports C-type and D-type tripping characteristics: C-type: suitable for general resistive loads and light inductive loads. D-type: suitable for equipment with high starting current, such as motors and transformers. The residual current protection function supports multiple operating current options, including 15mA, 30mA and 50mA, effectively reducing the risk of electric shock and electrical fire caused by leakage faults. The DZ47TRLE series complies with GB/T 16917.1 standard and has obtained CCC certification. It is suitable for residential distribution boards, small commercial facilities, industrial terminal protection and temporary power systems.
