NOARK Αυτόματος διακόπτης 1P Τύπος B 16A 6kA AC

NOARK Circuit Breaker 1P B 16A 6kA AC

The modular circuit breakers of the Ex9BN series are universal devices for all types of applications meeting the high requirements of standards for household use in accordance with EN 60898 in the range of rated currents from 1 to 63 A.  The rated short-circuit breaking capacity Icn is 6kA.In each case Icn refers to all versions of the circuit-breakers, i.e. for rated current up to 63 A and tripping characteristics B, C, D.

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.Trigger characteristics: B, C, D.With regard to mechanical parameters, the Ex9BH and Ex9BN series are fully compatible.

They can be combined with a wide range of accessories, including auxiliary contacts, auxiliary trip contacts, shunt releases, undervoltage and overvoltage releases or differential blocks.It is possible to create various combinations of accessories.These combinations are limited only by the total number, not the type, of accessories – all elements fit together.Up to three auxiliary contact units or auxiliary tripping contacts and up to two trip units can be fitted.
