NOARK 3P overcurrent circuit breaker Type B 50A 6kA AC (100058)

A miniature circuit breaker is a component of an electrical system whose task is to break the continuity of a circuit when the current exceeds the safe value for that circuit. The circuit breaker is designed to control and protect against the effects of overloads and short circuits of consumer circuits of installations, as well as electrical equipment in households. Designed for multiple use. Characteristics of a device with a small starting current: heaters, household appliances, etc.

SERIES CHARACTERISTICS:

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

The Ex9BH series miniature circuit breakers 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. With regard to mechanical parameters, the Ex9BH and Ex9BN series are fully compliant.

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

COMMON FEATURES OF THE SERIES:

• Miniature circuit breakers according to IEC/EN 60898-1
