Eaton PPFi

CLASS II:  Point of Entry and Secondary Protection

Product Features

The Eaton PPFi is designed to provide point-of-entry (Category C) & sub-circuit protection (Category B) against power surges caused by external sources such as lightning strikes & substation switching as well as providing a measure of protection from surge events generated on the secondary side of the filter.  An ideal device for all Category locations.

The Eaton PPFi is a 3-stage protection system utilizing primary & secondary MOV protection in conjunction with a Low-Q LC filter.  The unit provides filtering of the line harmonics, noise & RF transmitters with a cut-off frequency of <10Hz & a minimum attenuation of 70dB above 1MHz.  Special care has been taken in the design of the filter to minimize ringing caused by light loads, surge diverter operation & inductive load back-EMF.

All models in the PPFi Series are fully enclosed in wall mounting IP24 steel enclosures.  A graphical mimic display provides at-a-glance indication of the status of the PPFi with indicators showing correct functions in green & faults in red.  The alarm function provides a summary alarm output for protection failure & power failure.
