xPole Combined RCD/MCB Device PKN6/PKNM, 1+N-pole
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.

PKN6:
- Increased trip fault resistance (type G) due to delayed tripping
and increasd current resistance > 3 kA
PKNM:
- Higher resistance to nuisance tripping (type F, G or G/A) due to
time delayed tripping and increased current withstand capability > 3 kA - Also available in 110 VAC version!
Line- and residual current protection
Suitable types for all contingencies
- Type -A: Protects against special forms of residual pulsating DC which have not been smoothed.
- Typ -G: 10 ms time delay in order to avoid unwanted tripping (e.g. during thunderstorms).
- Type AC: This type only detects pure sinusoidal AC residual currents.
- Type -F (PKNM): Increased protection in applications with 1-phase frequency converter due to the detection of mixed frequencies, higher load capacity with smooth DC fault currents up to 10 mA.
