Wylex Three Phase MCB ( Type C ) - 10kA
Rated 20 Amps
Three Phase Distribution Board use
Black Retaining clip
Type C devices are capable of supplying the majority of inductive and capacitive loads such as motors and transformers.
Surges on energisation, for example with discharge lighting, may well reach 25 times the rated current of the device, but only for very short duration.
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.
If you are fitting to an existing Wylex TP Board
Please check the colour of the retaining clip on the back of the existing MCB's
