Use SD – MULTIMOV high energy surge diverters for single phase point of entry protection at main switchboards. Models are available for all wiring systems worldwide. SD MULTIMOV surge diverters feature a parallel redundant arrangement of high energy metal oxide varistors (MOVs), thus promoting long life and exceptional surge handling capacity. In the event of a varistor failure the remaining segments continue to provide protection. A digital display confirms the device rating by displaying the percentage active of the redundant segments. The display indicates segment status and thermal overload. A failsafe alarm contact allows for remote monitoring.
Use MULTIMOV all mode high energy surge diverters for point of entry protection at main switchboards, especially where N-PE protection is required. MULTIMOV surge diverters feature a parallel redundant arrangement of high energy metal oxide varistors (MOVs), thus promoting long life and exceptional surge handling capacity. In the event of a varistor failure the remaining segments continue to provide protection. The LED display indicates segment status and indicates normal operation when all LEDs are brightly lit.
The Novaris Surge Circuit Breakers are designed specifically for short circuit protection of MOV based Type I and Type II (point of entry and secondary) shunt connected surge diverters. The SCB models have a continuous current rating of 3A to power the Novaris active alarm circuits but will not trip for large transient surges.
The Novaris HSF is a hybrid surge filter with primary and secondary hybrid surge protection components plus a low pass filter. The hybrid design means the filter can continuously withstand phase to phase voltage between its phase and neutral terminals yet its performance equals that of other Novaris surge filters. This makes it ideal for applications where voltage regulation is poor and power line faults common.
Novaris SSP protectors are suitable for installation in circuits up to 63A. The SSP range has been engineered to provide excellent performance in an economical package. Protection is provided for all combinations of lines (L-N, L-PE, N-PE) ensuring the maximum level of protection is achieved at all times. Series surge protectors house the shunt (parallel) connection of the protection components internally within the device. This reduces the connection impedance to a minimum to guarantee optimal performance in all installations.
Use Spark Gap Surge Diverters for point of entry protection at main switchboards where direct strike protection is required. Carbon disk spark gaps are a robust and proven technology designed to handle long duration surges. The low resistance design minimises the energy dissipation within the device. Two models are available with either 50 kA or 110 kA of impulse current handling per phase for even the most extreme lightning environments. The Novaris spark gap diverters are a sealed unit and do not exhaust hot ionised gas into the switchboard.
