Rated 5 out of 5 by from Does what it says. Easy fit 6A MCB. Make sure you get the right size - although they're both called "Type B" and they do the same job, the BG and Wylex (NHX...) ones, aren't interchangeable - i.e. they don't both fit the same Consumer Unit mounting rail. Check which ones you already have and then get more of the same.

Type B - Magnetic Operating 3 to 5 Times In (Current Rating) What does this mean?

Asked by: Trevtreva
Hi Trevtreva, That is the technical specification of the MCB, as per the relevant standards, Type B (should really be B _Curve_) refers to the response times for given fault levels graph and is the most commonly used curve for domestic properties, Magnetic Operating confirms that it is not using the older Mechanical Operating style of mechanism, and 3 to 5 times In is referring to the " i " measurement of incoming current.

DIN rail size.

What width of DIN rail does this fit?
Asked by: Kintara
Hi Kintara, We are only aware of one standard DIN rail size (35 mm +/- 0.5mm), which this and all of the other BG Circuit Protection range devices are designed to fit.

Compatibility

Are these circuit breakers compatible with the hager consumer units?
Asked by: Sadamsue
Hi, thank you for your product enquiry. British General have not had any rival manufacturers' circuit protection enclosures or devices in for comparison testing, so we cannot say whether our devices would be compatible with anyone else's consumer units or not.
