FAQs
What is the purpose of a Miniature Circuit Breaker (MCB)?
An MCB protects electrical circuits from damage caused by overcurrents and short circuits by automatically interrupting the current flow.
What does 'B Curve' mean?
B curve MCBs are designed to trip quickly on overload and are suitable for general-purpose applications. The tripping characteristic is suitable for lighting circuits, socket outlets, and small appliances.
What is the short circuit rating?
The short circuit rating indicates the maximum fault current the MCB can safely interrupt, which for this model is 6kA.
Where should I install the MCB?
The MCB should be installed within a distribution board, mounted on a DIN rail.
Can I replace the MCB myself?
Replacing an MCB requires working with electrical circuits, and it's recommended to have a qualified electrician perform the replacement to ensure safety and compliance with regulations.
What is the voltage rating of this MCB?
The voltage rating is 230V, making it suitable for standard electrical systems.
What is the warranty period?
The product has a 1-year guarantee.
