SPFi Series - 100–400A, 80–240kA. Designed to provide point-of-entry and sub-circuit protection against power surges caused by external sources such as lightning strikes and substation switching as well as providing a measure of protection from surge events generated on the secondary side of the filter.

The SPFi is a 3-stage protection system utilising primary and secondary MOV protection in conjunction with a Low-Q LC filter.
In addition, the unit also provide filtering of the line harmonics, noise and RF transmitters with a cut-off frequency of <10kHz and a minimum attenuation of 40dB above 1MHz.

All models in the SPFi Series are fully enclosed in wall mounting IP24 steel enclosures. A graphical mimic display provides at-a-glance indication of the status of the SPFi with indicators showing correct functions in green and faults in red.

The alarm function provides a summary alarm output for protection failure and power failure.
