These PFL6/7 devices are line voltage-independent electromechanical residual current protection units with integrated overcurrent protection.
This PFL6 RCD/MCB combination of the "Economy series" is only available as type AC (up to 250 A impulse current resistant) with rated currents of 6 to 25 A.
The PFL7 device is not only available as AC and pulse current sensitive "standard type" A, but also as type G, which triggers with a time delay of at least 10 ms, and as AC. While the AC and the A are only impulse current resistant up to 250 A, the type G offers an increased impulse current resistance of more thank 3 kA. This makes it the ideal choice when nuisance tripping must be avoided.
