To view this video, CIRCUIT BREAKERS – SELECTING TYPES, click on the link below

This is an introduction to the selection of MCB types and how a knowledge of inrush currents at start up can influence the choice of device.

We look at thermal sensing of overload currents and electro-magnetic responses to short circuit and fault currents.

Should a type B or type C be installed, and what are the implications on safety and circuit performance.

And we also look at the different kinds of devices, single pole, three pole, four pole etc.

This video is a good overview of the subject.

This video is No.71 on our YouTube channel where we have videos on a wide range of electrical topics.
