It is electro-mechanical in nature. The highlight here is that it can be wired in either direction. This makes retrofit a breeze with regards to matching wiring conventions. it is also busbar compatible. |  |
In addition to fault currents in the Ac and pulse current range, type B also detects Dc fault currents, which can occur in frequency inverter controls, photovoltalc systems as well as through the electronic use in households, and increases safety considerably
Applications with:
•Appliances and motors with 1Phase frequency converters with •PFC([Power factor compensation)or
•1 phase frequency converters supplied between phase/phase or
•3 phase frequency converters
•DCsystems( photovoltaic systems,ups units...)
•In front of PVSystems/Battery banks/UPs Units/EV charging
•Medical devices/Frequency converters/Motor controllers
•Sensitive to all residual currents according up to 1kHz.
