Wylex MCB NHXB20
Wylex 20 amp Type B MCB

For use in all Wylex domestic ‘NH’ consumer units. The ‘NHX’ range of RCBOs and MCBs replace the now obsolete ‘NSB’ range.

This MCB is a ‘B’ Type breaker and will thus trip between 3 and 5 times the full load current which is suitable for most domestic installations. If you are at all unsure you should check with a fully qualified electrician.
