The PeakTech 2710 is an RCD tester, which is used to determine the tripping currents and the tripping times of residual current circuit breakers, which are used in every new building according to current building regulations. Residual current circuit breakers are used for personal protection and switch off a circuit when a residual current is registered, which flows off via the protective earth (PE). RCD testers allow a residual current to flow and thus determine at which residual current the RCD trips. Furthermore, the tripping time is also measured. These two parameters, tripping current and tripping time, are the safety-relevant parameters of an RCD. The various selectable test currents and characteristics that can be set on this device make the PeakTech 2710 the ideal companion for every electrician.
