The primary difference between 10kA and 6kA RCBOs is their short-circuit current rating.
10kA RCBOs: Short-Circuit Rating: 10kA (kiloamperes).
10kA RCBOs are designed for use in environments where higher fault currents are possible, such as industrial or commercial installations. The 10kA rating means that the RCBO can safely interrupt a short-circuit current of up to 10,000 amperes without damage.
10kA RCBOs provide a higher safety margin, making them suitable for installations with higher fault current levels.
6kA RCBOs: Short-Circuit Rating: 6kA (kiloamperes).
6kA RCBOs are generally used in residential or light commercial environments where fault currents are expected to be lower. The 6kA rating means the RCBO can safely interrupt a short-circuit current of up to 6,000 amperes without damage.
6kA RCBOs are often more cost-effective for installations where lower fault currents are anticipated, providing adequate protection without the need for higher ratings.
