This residual current operated circuit breaker with integrated overcurrent protection in 1+N pole is a high-quality residual current circuit breaker and miniature circuit breaker combination.
This combined RCD/MCB PKN6 device is not only available as AC and pulse current sensitive "standard type" A, but with a time delay of at least 10 ms as type G. While the AC and A are only impulse current resistant up to 250 A, the type G offers an increased impulse current resistance of more than 3 kA. This makes it the ideal choice when nuisance tripping needs to be avoided.
This RCD/MCB combination PKNM switch is not only available as an AC and pulse current sensitive "standard type" A, but also as a mixing frequency sensitive type F, as a type G or G/A triggering with a time delay of at least 10 ms. While the AC and the A are only impulse current resistant up to 250 A, the other three types F, G and G/A offer an increased impulse current resistance of more than 3 kA.
