Ex9BN miniature circuit breakers are suitable for domestic as well as industrial applications. They can be combined with wide range of accessories including auxiliary and signal contacts, shunt trip release, undervoltage and overvoltage release or RCD add-on block. It is possible to create diversed combination of accessories. These combinations are only limited by total number, not by the type of accessories - all components fi t together. It can be used up to three units of auxiliary or alarm contacts plus up to two units for release units.
