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.
3-Phase Protection: Configured as 3P or 3P+N (3 poles + neutral) to safeguard 3-phase circuits with a rated current of 63A.
Type B Tripping Characteristic: Instantaneous tripping for currents between 3–5 times the rated current (3In–5In), ensuring rapid response to overloads and short circuits.
Dual Safety Mechanisms: Combines overcurrent protection (overload/short circuit) and residual current protection (30mA–300mA sensitivity) to prevent electric shock and fire hazards from insulation faults.
Wide Voltage Compatibility: Operates at AC 50/60Hz, 400VAC, suitable for global 3-phase electrical systems.
