SERIES CHARACTERISTICS:

Modular overcurrent circuit breakers of the Ex9BN series are universal devices for all types of applications meeting the high standard requirements for domestic use in accordance with EN 60898 in the current rating range from 1 to 63 A. The rated short-circuit breaking capacity Icn is 6kA. In any case, Icn applies to all versions of the circuit breakers, i.e. up to 63 A rated current and B, C, D trip characteristics.

The overcurrent circuit breakers of the Ex9BH series are available in 1, 1+N, 2, 3, 3+N, 4 -pole versions, where the pole width corresponds to one module - 18 mm. Tripping characteristics: B, C, D. In terms of mechanical performance, the Ex9BH and Ex9BN series are fully compatible.

They can be combined with a wide range of accessories, including auxiliary contacts, auxiliary trip contacts, rising, undervoltage and overvoltage triggers or residual current blocks. Various combinations of accessories are possible. These combinations are limited only by the total number, not the type of accessories - all components fit together. Up to three auxiliary contact units or tripping auxiliary contacts and up to two trip units can be fitted.
