There are many situations where a traditional RCD or RCBO does not offer protection. A traditional RCD isolates power when there is a current imbalance between the active and neutral conductors (fault to Earth). To do this the RCD generally relies on good earthing integrity and a low earth impedance.  

The Powersafe RCD DUO offers a much broader range of protection by operating in various earthing environments. The RCD DUO is designed to isolate power in the occurrence of a fault to earth on MEN and IT type systems. The RCD DUO is connected to the earth circuit, which however is not required to be earthed, so the need for earth staking generators is a thing of the past.  Generally, at 40 volts (the potential point to electrocute) the device will trip at 10mA. This can be altered to meet the application at the point of assembly. 

Unlike many other devices on the market the RCD DUO has no relays or coils with moving parts and therefore is not subject to vibrations caused by generators and transportation. 

Did you know that portable RCD boards will not protect you on most portable generators? The RCD DUO combines a traditional RCBO and a unique Earth Sensing Device which physically monitors the Earth circuit for voltage and current.
