LPI® SS480 Surge Filters 32A, 40A, 63A

· Product Description

· Designed to suit TT, TN-C, TN-S, TN-C-S & IT distribution systems

· Non-saturating inductors – dv/dt and di/dt of the incoming surge willbe reduced by 1000 times· Primary (160kA 8/20μs) and secondary (40kA 8/20μs) surgeprotection

· High N - E protection – 100kA 10/350μs or 150kA 8/20μs

· Surge Counter (optional), LED status indication

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, orinductive, capacitive coupling. Efficient filtering and clamping at the point of entry to sensitiveelectronic equipment is essential to mitigate physical equipment damage, loss of operations andeconomic loss.

The LPI Surge Filter provides multiple stage protection against incoming surges & transients andshall be installed in series with the incoming 220-277Vac single phase (Phase – Neutral) mainspower supply to the equipment or building. Shunt-only clamping alone is not sufficient, as it doesnot 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 10V/μs as per AS1768-1991 Cat B 3kA8/20μs applied impulse and to below 30V/μs for AS 1768-1991 Cat C 20kAμs applied impulse.

The Surge Filter is designed for multistroke lightning events and comes with the SS140-480 asthe primary protection rated at 160kA 8/20μs per phase as the first stage to absorb the majority ofthe energy. The SS offers the ultimate level of safety and reliability whilst retaining optimumprotection levels critical for electronic equipment. SS ensures that the protection device is virtuallyimmune to the effects of 50/60 Hz sustained over voltages, allowing fault voltages up to 480Vac.

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 filterattenuates noise and any harmonics present on the power system and is designed to attenuatetransverse and common mode noise. The third stage consists of further surge diverters rated at40kA 8/20μS connected across the load side, these are designed to suppress surges generatedby load side equipment.

LPI Surge Filter limits the voltage differential due to a lightning induced impulse between phaseand 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 10/350μs (or 150kA8/20μs) is provided to limit feedback currents if the site earth goes high potential with respect tothe sub-station or transformer earth. This is a common occurrence due to a near-by direct strike.
