Description
Wylex RCBO NHXSBS1C40Wylex 40 amp Type C RCBOFor use in all Wylex domestic 'NH' consumer units. The 'NHX' range of RCBOs and MCBs replace the now obsolete 'NSB' range.
What is an RCBO?
RCBOs combine the functionality of an RCD, which protects against earth leakage, with that of an MCB which protects against overloads and short circuits. The new 17th edition regulations, which dictate that all circuits must be protected against earth leakage, have made the use of RCBOs more prevalent. You should use a Wylex RCBO in conjunction with a Wylex consumer unit, ensuring that the RCBO is designed for use within that particular fuse board as not all Wylex RCBOs will fit all Wylex fuse boards. Wylex NSBS RCBOs such as this one will fit all Wylex NH fuse boards.
