LPI® SST Surge Filters

Features
• High performance surge protector for an operating voltage of 200 - 240Vac
• Designed to withstand fault and over-voltage conditions of up to 385Vac, as per IEC61643
• Impulse discharge current 100kA + 50kA 8/200s Ph-N
• Three stage protection provides highest level of protection for sensitive electronic equipment

Product Description
• Designed to suit TT, TN-C, TN-S, TN-C-S & IT distribution systems
• Non-saturating inductors – dv/dt of the incoming surge reduced up to
1000 times
• Primary (100kA 8/200s) and secondary (50kA 8/200s) surge protection
• High N - E protection rating – 100kA 10/3500s or 150kA 8/200s
• Status indication and optional surge counter

Electronic equipment is highly susceptible to damage from lightning and other transient pulses (including man made switching transients), which arrive via the powerlines through direct strike, or inductive and capacitive coupling. Efficient filtering and clamping at the point of entry of power feeds to sensitive electronic equipment is essential to mitigate physical equipment damage, loss of operations and economic loss. 

The LPI Surge Filter provides multiple stage protection against incoming surges & transients and shall be installed in series with the incoming 200-240Vac single phase (Phase – Neutral) mains power supply to the equipment or building. Shunt-only clamping alone is not sufficient, as it does not limit the excessive wavefront characteristic of the pre-clamped waveform.

The LPI Surge Filter will reduce the rate of rise of voltage (dv/dt) to below 15V/0s as per AS1768 Cat B 3kA (8/200s) applied impulse and to below 30V/0s for AS 1768 Cat C 20kA (8/200s) applied impulse.
The Surge Filter is designed for multistroke lightning events and comes with the SST (Smart Surge Technology) as the primary protection, rated at 100kA 8/200s per phase, as the first stage to absorb the majority of the energy. The SST offers the ultimate level of safety and reliability whilst retaining optimum protection levels critical for electronic equipment. SST ensures that the protection device is virtually immune to the effects of 50/60 Hz sustained over voltages, allowing fault voltages up to 385Vac, in accordance with IEC61643 requirements. 

The second stage consists of low pass non-saturating inductors and capacitors (L-C Filtering) which further attenuates the let-through voltage already clamped by the primary stage. The filter attenuates noise and any harmonics present on the power system and is designed to attenuate transverse and common mode noise. The third stage consists of further surge diverters rated at 50kA 8/20μS connected across the load side. These are designed to suppress surges generated by load side equipment. 

LPI Surge Filter limits the voltage differential due to a lightning induced impulse between phase and neutral as well as from neutral to ground. Thus providing both common mode and differential (transverse) mode protection. Neutral to earth protection rated at 100kA 10/3500s (150kA 8/200s) is provided to limit feedback currents if the site earth goes high potential with respect to the sub-station or transformer earth. This is a common occurrence due to a near-by direct strike.
