    surge protection  SFH - 2000A Surge Filters
    Product Features
    Compliant with the relevant IEC lightning and surge protection standards, in particular IEC 62305 and IEC 61643. All Mode Protection - Novaris models featuring all mode protection provide protection for all combinations of lines (L-N, L-E, N-E) ensuring the maximum level of protection is achieved at all times. They have been designed for installation in any wiring system worldwide. Multistage Transient Protection - Models featuring multistage transient protection deliver greater levels of protection through a staged approach. The primary stage absorbs the majority of the surge energy. The remaining stages provide accurate clamping and a degree of redundancy. Redundant Segments - Models featuring redundant segments have a parallel redundant arrangement of high energy metal oxide varistors (MOVs), thus promoting long life and exceptional surge handling capacity. Thermal Sensing - Sustained overvoltages can cause components to overheat and degrade. Percentage Active Display - A digital display confirms the device rating upon switch on then displays percentage active. The display indicates segment status and thermal overload. LED Status Display - LED indicators are provided on models to indicate operating status. External Alarms - Models featuring external alarms have voltage free changeover contacts for remote status indication. Safe Metal Enclosure - Novaris surge protection products are housed in safe, all metal enclosures. In the event of a prolonged overvoltage they will not catch fire or explode.
    Product Description
    Novaris SFH surge filters provide the highest level of protection with the lowest let through voltage.  When installed at a main switchboard Novaris surge filters will protect all connected equipment.
