MSFi Series - Single and Three-phase Surge Filters

The MSFi is designed to provide point-of-entry 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 MSFi is a 3-stage protection unit 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. Special care has been taken in the design of the filter to minimise ringing caused by light loads, surge diverter operation and inductive load back-EMF.
