Wylex Plug-in 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 Plug-in Domestic MCBs have a short circuit breaking capacity of 3000A (M3).
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.
