The AEG Elfa 90 Modular System grows

Maximum protection capacity for the loads of modern electrical installations.

The AEG Elfa 90 system adds two new types of products to its range, designed to ensure the highest levels of protection as defined by the standard EN62423.

Class F RCDs, in addition to having the ability to protect for leakage currents of sinusoidal type and pulsating unidirectional like in the A and AC classes, are also able to intervene in the presence of current faults with different frequency, up to 1kHz. For example there is the case of faults which may be generated at the output terminals of the frequency converter (inverter), characterised by high frequencies of up to 1 kHz.

The series' cutting edge for completeness and responsiveness to the EN62423 standard is the class B differential switch, which is able to intervene for all types of earthing residual currents. These devices are sensitive to leakage currents just like the A and AC classes, but also to leakage currents at class F high frequencies as well as to continuous residual currents.

The leakage currents are generated from the continuous loads are present inside rectifier bridges: UPS, inverters for AC motors, AC/DC converters, DC/AC converters (PV inverter). For these types of loads, which are very frequent in modern electrical systems, the use of class B circuit breakers is necessary.
