China wholesale Dc Doorbell Transformer Factories – SL7 Magnetic RCBO, high class market, mass production reliable 6kA Ics breaking capacity. – Sofielec Electrical

Product Description

When the current in the power supply exceeds the maximum current value set in advance, the leakage circuit breaker will automatically disconnect, which plays a role in protecting the power supply, so as to avoid unnecessary safety accidents. In the wiring diagram of the leakage circuit breaker, there are leading and live wires. In the case of no leakage, the live wire and the neutral wire are in opposite directions and the current is equal. When there is leakage, a magnetic force will be generated, and the current will vary, which will disconnect Leakage circuit breaker for protection

Range of application

SL7 series of leakage circuit breaker is applicable for 230V AC voltage, 50HZ frequency, 40A rated current, and single-phase circuit and rated current below 40A. The breaker has the functions of leakage, overload and short circuit protection, can mainly be used for electric shock protection to prevent fire risk caused by ground connection fault of equipment, and adopts of electromagnetic/electronic leakage tripping system. Operative standard:GB16917 & IEC61009
