Low Voltage Power Protection, Conversion & Flexible Conductors
The image on the left is where lightning directly strikes the building’s Lightning Protection System (LPS). In this instance, the current flows into the local LPS earth system, causing a local earth potential rise. In this event, some of this lightning current actually flows out through the point-of-entry SPDs seeking the distant earth of the power supply system
Higher level of protection, known as Class I protection, or point-of-entry is required for the scenario mentioned above when the building has external lightning protection (lightning rod).
Main Features Of SPD (Surge Protection Device At Point-Of-Entry High Risk)
- The Surge Diverter shall operate at a Nominal system Voltage of (Vrms) 240/415V, 50 Hz.
- The Maximum Discharge Current, Imax, as defined in IEC 61643-11 shall be 100kA, 8/20µs, per phase.
- The Nominal Discharge Current, In, as defined in IEC 61643-11 shall be greater than 40kA, 8/20µs, per phase
Maximum Discharge Current (Imax): The maximum single shot current, having an 8/20μs waveshape, which the SPD can safely divert.
Nominal Discharge Current (In): The peak value of the current flowing through the SPD during the application an 8/20μs waveshape.
Conducted Lightning Energy: Direct strike to overhead lines but at distance. Class II surge protection devices are recommended in this type of scenario.
Class II SPDs would be installed where the surge currents are expected to be less. This could be at the main power entry point of a building in a non-exposed location (surrounded by taller
buildings, for example), or at sub-panels within the building.
Main Features Of SPD (Surge Protection Device At Point-Of-Entry Medium Risk)
- The Maximum Discharge Current, Imax, as defined in IEC 61643-11 shall be 50kA, 8/20µs, per phase.
- The Nominal Discharge Current, In, as defined in IEC 61643-11 shall be greater than 20kA, 8/20µs, per phase.
- Incorporate individual surge modules that allow replacement without disconnection of power
- Have visual indication and voltage free contacts
- Standards: AS1768:2007, IEC 61643-11:2011, EN 61643-11:2012 and UL 1449, 4th Edition
Maximum Discharge Current (Imax): The maximum single shot current, having an 8/20μs waveshape, which the SPD can safely divert.
Nominal Discharge Current (In): The peak value of the current flowing through the SPD during the application an 8/20μs waveshape.
Normally DB’s do not have a N-E link so, according to AS/NZS 1768:2007, at DB’s surge protection should be applied between Phase, Neutral and Earth. Some models of single and three-phase surge diverters in this section are multimode and protect across P, N and E but alternatively, multiple single-mode SPDs may be used.
Fitting SPDs at all three locations may not be necessary, depending on the building size, and wiring length. Generally, SPDs are always fitted at the point of entry, and in smaller equipment rooms may just be, additionally, at the equipment.
In larger buildings, spread over multiple floors or large areas, SPDs would usually be provided at the distribution boards, and additionally at sensitive or critical equipment

Lightning or induced surges can destroy or compromise signal communications systems and data. nVent ERICO offers multiple series of data and signal surge protection devices designed to provide transient protection for equipment from induced surges. These are also well-suited to the protection of industrial equipment and are compact in
size, while offering high surge carrying capacity. nVent ERICO data and signal surge protection offers a complete solution to eliminate damage, downtime, and power disruption..
The selection of an SPD for communication and signalling circuits requires knowledge of the:
- Maximum Continuous Operating Voltage (Uc)
- Maximum line current (IL)
- Frequency
- Termination (connector type and/or impedance
Where a protocol is known, this often eliminates the need to verify product selection criteria 1-3, and occasionally 4
