Circuit breaker 6 kA, type B

Circuit breaker 6 kA, curve B, 10 A, 3-pole Suitable for use in photovoltaic systems.

The miniature circuit breakers Ex9BN are suitable for both domestic and industrial applications. They can be combined with a wide range of accessories, including auxiliary and signaling contacts, side trip units, undervoltage and overvoltage releases, or additional RCD blocks. It is possible to create various combinations of accessories, and the limitations apply only to the total number, not the type of accessories – all components are compatible with each other. Up to three auxiliary or alarm module and up to two trip modules can be used.
