Frequently Asked Questions
What is the primary function of an RCBO?
An RCBO (Residual Current Breaker with Overcurrent protection) combines the functions of an MCB and an RCD. It protects against overloads, short circuits, and earth leakage currents (residual current).
What do the B, C, and D tripping curves signify?
These curves represent the instantaneous tripping current: Type B (3-5 In) for residential, Type C (5-10 In) for general commercial/industrial, and Type D (10-20 In) for high inrush current equipment.
Can this circuit breaker be used for fire protection?
Yes, it provides protection against fire hazards caused by insulation faults through its residual current sensing capabilities.
What is the breaking capacity of the YCB6HLN-63 model?
This model has a rated short-circuit capacity (lcn) of 4500A, which is suitable for most residential and standard commercial applications.
Is the installation of this device easy?
Yes, it is designed for mounting on a standard 35mm DIN rail (EN60715) using a fast clip device, making it compatible with most modern distribution boards.
What is the temperature range for safe operation?
The device is designed to operate in ambient temperatures ranging from -5ºC to +40ºC, with a storage temperature range of -25ºC to +70ºC.
