Circuit Protection Review 
Circuit breakers are easily switched on and off which can cause problems for professionals carrying out an intervention. Shocks and extreme injury can be the results of prematurely reactivating a circuit.
Siemens has developed a new miniature circuit breaker (MCB) with a switching capacity of 10 kilo amperes (kA), which can be used especially in non-residential and industrial buildings.
Choosing the right devices for final circuit protection can be a confusing task: modern MCBs, RCCBs and RCBOs are available in a bewildering array of types and sizes. To help resolve this confusion, David Pitt of Eaton’s Electrical Sector provides some useful guidance.
E-T-A Circuit Breakers has introduced a new compact thermal-magnetic circuit breaker type 2216-S, increasing its plug-in mounting product range for automation in industrial and buildings applications.
