FAQ

Question?

What is the difference between a Type AC and a Type A RCBO?

A Type AC RCBO, like this model, is designed to trip on sinusoidal AC residual currents. A Type A RCBO trips on both sinusoidal AC and pulsating DC residual currents, offering a higher level of protection for circuits with modern electronic devices.

What does the 'C10' marking signify on this Legrand breaker?

The 'C' indicates the tripping curve, which is suitable for general applications with moderate inrush currents (e.g., lighting, socket outlets). The '10' indicates the rated current, meaning it will trip if the continuous current exceeds 10 Amperes.

Is this 1P+N RCBO suitable for a three-phase system?

This is a single-phase (1 Pole + Neutral) device and is designed to protect a single-phase circuit. For a three-phase system, you would need a 3P or 3P+N RCBO to protect the entire system, or you could use individual 1P+N RCBOs on each single-phase circuit derived from the three-phase supply.
