YCB7NLE-63 series RCBO is suitable for AC 50/60Hz, rated voltage up to 400V, rated current up to 63A circuits. It is used for leakage and overload protection for similar purposes to prevent fire or casualties caused by line leakage or electric shock.
1. Protection against overload and short-circuit currents.
2. Protection against the effects of sinusoidal alternating earth fault currents.
3. Protection against indirect contacts and additional protection against direct contacts.
4. Protection against fire hazard caused by insulation faults.
5. Used in residential building.
6. According to the type of instantaneous release classified as follows : type B(3-5)In, type C(5-10)In, type D(10-20)In.
1. Ambient temperature: -5°C~+40°C
2. Relative humidity: ≤50% at 40°C; ≤90% at 25°C
3. Altitude: ≤2000m
4. Environmental conditions: no harmful gases and vapors, no conductive or explosive dust, no severe mechanical vibration
