Feature: 1. MAIN FUNCTION: Leakage circuit breaker with overload and short circuit protection functions, which is used to protect the circuit from overload and short circuit. 2. SAFE OPERATION: If the electric shock or leakage current exceeds the specified value, the power supply can be automatically cut off in a short time to provide safety. 3. PA66 HOUSING: The circuit breaker shell is made of PA66, which is environmentally friendly and durable, with good pressure resistance and rust resistance. 4. GOOD PERFORMANCE: Type A leakage protector not only protects AC leakage, but also protects DC pulsating leakage, with high breaking capacity and sensitivity. 5. MULTIPLE USAGES: Applicable to home decoration, engineering, rural network transformation and other projects to meet all the basic needs of users. Specification: Item Type: Circuit Breaker Model: BYDB1L 63 Material: PA66 Rated Current: 20A Leakage Protection Current: 30mA Rated Voltage: AC 230V 50/60Hz Class: Type A Icu: 6KA Type A is more comprehensive and safe than AC for leakage protection. The human body electric shock, electrical equipment damage and electrical fire caused by DC pulsation leakage occur from time to time, causing casualties and property losses that should not have occurred, which has attracted the attention of government departments and industry personnel. . Package List: 1 x Circuit Breaker Note: Generally, it cannot be used as a frequently switched wire.
