Zdanie w moim tekście brzmi tak:

We recommend the use of residual current circuit breakers (RCCB) with a trip threshold of 300 mA and delayed tripping (super-resistant, characteristic K).

Jako że pierwsze słyszę o czymś takim, to sprawdzam w necie. Jest w tekście Siemensa, str. 29. dokumentu:

2.4.7 Type K, super-resistant
Leakage currents and residual currents arising from the operation of electrical equipment cannot be distinguished. The reaction to
both is the same. If a temporary high leakage current occurs, it is neither necessary nor desirable to disconnect the load from the
supply. If electronic equipment is used with capacitors connected against the protective conductor in order to eliminate faults,
inadvertent tripping of the RCCB can occur when the equipment is switched on.

In order to avoid this disconnection, the use of super-resistant residual current protective devices is recommended. They trip with
a time delay and are designated as Type K devices.
As far as the product standards EN 61008-1 (RCCBs) and EN 61009-1 (RCBOs) are concerned, there are only two types of device:
– Standard
– Selective
For these types of device, the limit values for the break times are defined. In accordance with the standard, the super-resistant residual current protective devices are instantaneous versions.
