Guide to Miniature Circuit Breakers (1)

The SAFEhouse Association has published a number of user-friendly guides to provide technical overviews, regulatory information and buying guidelines for the South African electrical industry.

Pierre Nothard, chairman of the SAFEhouse Association, says the prevalence of sub-standard electrical products in South Africa is partly due to misinformation and a lack of information. In an effort to address these issues, the SAFEhouse Guides, which have been authored by industry specialists, provide information that is relevant, concise, and that promotes compliance and electrical safety.

 

A SAFEhouse Guide to Miniature Circuit Breakers - Part 1

SAFEHouse Guide to Miniature Circuit Breakers CoverThis illustrated guide explains what a miniature circuit breaker (MCB) does, what it consists of and how it works. It describes the typical internal construction of a thermal magnetic type MCB and gives an overview of the two technologies: thermal magnetic and hydraulic magnetic; what makes them work and why. The MCBs electrical characteristics – voltage rating, current rating, overload characteristics and breaking capacity – are described along with time delay curves and breaking capacity. Information that covers the required marking and information on MCBs is given along with a list of the applicable standards for MCBs.
