Wylex MCB's detect overcurrents due to both overload and fault currents.
The MCB will operate and interrupt the supply to prevent damage to the installation.
  • Wylex Commercial MCBs have a short circuit breaking capacity of 10000A (M10).
  • The current carrying capacity of the cable should always exceed the current rating of the MCB to prevent damage.
  • The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate.
  • When in the off position, a contact gap of 4 mm is achieved. Wylex's MCBs may therefore be used as triple pole isolating switches where appropriate.
