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 RCD. It protects against overloads, short circuits, and earth leakage currents, preventing both electrical fires and electric shocks.
What is the difference between B, C, and D trip curves?
These curves represent the instantaneous trip current. Type B trips at 3-5 times rated current (residential), Type C at 5-10 times (commercial/standard motors), and Type D at 10-20 times (high inrush current equipment).
Is this unit compatible with standard DIN rails?
Yes, it is designed for installation on standard DIN rail EN60715 (35mm) using a fast clip device for easy mounting.
What does the IP20 protection degree mean?
IP20 indicates that the device is protected against solid objects up to 12mm (like fingers) but is not waterproof. It is intended for indoor use within a protected distribution box.
Can this RCBO be used for both cable and busbar connections?
Yes, the terminal connection type is designed to accommodate both cable and Pin-type busbars, providing flexibility for different wiring configurations.
What is the rated short-circuit capacity of this model?
This model has a rated short-circuit capacity (Icn) of 4500A, making it suitable for standard residential and light commercial applications.
