Rated 5 out of 5 by Quality Trip Good price for quality and reliability from a trusted manufacturer 26 Apr 2015
Rated 4 out of 5 by Replacement Circuit Breaker Simple replacement of a Hagar circuit breaker that had melted due to a loose connection. Have used Wylex before and it fitted the Proteus Consumer unit without bother. I have always found Wylex mcb's reliable and expect this one to be no different. Only gave 3 stars for features because mcb's don't have any. 13 Apr 2015
Rated 5 out of 5 by Wylex 40A Single Pole Type B As usual, Wylex MCB's are solid and easy to work with. A quality product. 10 Jan 2015

Answer: 
Hi, The MCB you are referring to is an NHXB40 and cannot be mixed with NSB MCBs. The NSB MCB should be replaced with another NSB or alternatively all the MCBs in the board should be replaced using NHXB MCBs.
