Wylex NB30 MCB 30A SP Type 2 MCB

You can ensure the continued safety of your legacy electrical system by choosing the Wylex NB30. Manufacturers specifically designed this 30A single-pole breaker to protect against overloads and short circuits in residential properties. Therefore, it provides a stable and cost-effective solution for servicing older Wylex equipment.
Key Features include:
  • Type 2 Tripping Curve: This characteristic provides the historical equivalent to modern Type B protection. As a result, it handles standard domestic surges effectively while preventing nuisance tripping.
  • 6kA Breaking Capacity: This professional M6 rating ensures the device manages fault currents safely in typical household installations.
  • Clip-In Mounting: The breaker features a specialized clip-in mechanism. For this reason, you can install it quickly into compatible Wylex NN series boards.
  • Historical Compliance: This component conforms to BS 3871 standards. Consequently, it remains the correct technical match for many older UK electrical systems.
Please Note: This product is an obsolete legacy component. Although we supply it as a tested and reliable replacement, you should always consult a qualified electrician to ensure your installation meets current safety requirements.
