Miniature Circuit Breakers Ex9BH
Ex9BH series modular circuit breakers are universal devices for all types of application meeting the high demands of standards for circuit breakers for household use pursuant to EN 60898, with nominal currents range from 1 to 63 A. Short-circuit breaking capacity Icn is 10 kA. The Icn capacity above applies to all breaker versions, i.e. up to a nominal current of 63 A with D tripping characteristics.
Circuit breakers Ex9BH are supplied in 1, 1+N, 2, 3, 3+N and 4-pole design with pole width corresponding to one module (18 mm). Tripping characteristics B, C and D. Ex9BH breakers provides coloured control levers, with colours corresponding to the relevant circuit breaker’s nominal current. Since these levers are fully colour-penetrated, their colour coding is non-interchangeable.
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 fit together. It can be used up to three units of auxiliary or alarm contacts plus up to two units for release units.
