CONTENTS Page Type 2 (T2) self-protected surge protective devices (SPDs) with capacities Imax 20 kA and 40 kA for installations supplied with 230/400 V~ (50-60 Hz). This series is equipped with short-circuit protection that can occur at the end of the surge protector's life. Surge protective devices with L-N and N-PE protection modes (common and differential protection modes), the neutral (N) being protected by encapsulated spark gaps with higher power capacities than the phase protection. Also called mode "1+1” or "connection type 2” (CT2) according to standards HD/IEC 60364 clause 534. These SPDs are not suitable for this type of network, it is necessary to use SPDs 1Px2 or 2P. Uc of these SPDs are not suitable, it is necessary to use SPDs 1P/3P/4P with Uc 440 V~ According to this standard, SPDs are compulsory at the source of any new (or refurbishment) installation that is: - equipped with an LPS (lightning protection system) or lightning conductor (also see section 1.3.3) - supplied with overhead power lines when located in a geographical area classified AQ2 (Nk > 25) In the latter case, a lack of SPDs can however be justified by a risk analysis according to the UTE C 15-443 guide, standard IEC 60364-4-443 or any other recognised equivalent method. An SPD is obligatory in geographical areas classified AQ2 for certain installations: - with home-based medical services - equipped with security systems for people and property (fire alarm, technical or social alarms, etc). SPDs are usually recommended anywhere where the safety of people may depend directly or indirectly on the continuity of service of this equipment. The use of SPDs is also strongly recommended in mountainous areas, near large bodies of water or dominant structures (tall buildings, trees, etc), for installations at the end of a line or located less than 50 m from buildings equipped with a lightning conductor. Nk = keraunic level (number of days a year when lightning strikes occur in a given area) Ng = Nk/10 where Ng: number of strikes a year per km2. Installations with a lightning conductor or a LPS (or equipped with something that can act as a lightning conductor, such as a metal structure higher than the surrounding buildings, aerials, etc): - Type 1 or Type 1 + Type 2 SPD (Iimp > 12.5 kA) compulsory at the installation source (main distribution board in secondary buildings) - Installations more than 10 m high (apartment buildings, office buildings, hotels, etc): Type 2 SPD recommended for protecting private areas and floor distributors (communal areas) in addition to a Type 1 or Type 1 + Type 2 SPD - Installations with numerous private areas (apartment buildings, office buildings, etc): Type 2 SPD where In > 5 kA compulsory at the source of each private area if the Type 1 or Type 1 + Type 2 SPD cannot be installed at the installation source.

According to articles 443 and 534 of standards HD/IEC 60364 and guides TS/IEC 61643-12, the use of SPDs in new or renovated buildings is compulsory at the supply end of the installation in the following cases: - Buildings with lightning conductors or a LPS (T1 or T1+T2 SPD, limp > 12.5 kA) - Buildings with totally or partially overhead power supplies in AQ2 geographical areas (article 443.3.2.1 - AQ2: Nk > 25) and based on a risk assessment taking into account the type of power supply to the building (article 443.3.2.2) According to article 443.3.2.2, SPDs (Type 2) are also required in the following...

Self-protected surge protective devices SPDs and TN (TNC, TNS and TNC-S) earthing systems Transformateur HT/BT Conforming to standards EN 61643-11:2012 and IEC 61643-11 edition 1: 2011. These SPDs ensure compliance with the installation obligations and recommendations of standards NF C 15-100 (HD/IEC 60364) part 534, standards IEC/EN 62305 and guide UTE C 15-443 (TS/IEC 61643-12). Protection réseau 5. INSTALLATION 5.1 General principle Surge protective devices must not be installed in locations where there is a risk of fire or explosion without special provisions. They must be disconnected before...

Self-protected surge protective devices Connection with vertical supply busbar up to 40 A Cat. No 4 122 10/12/14/16 Mounting on lower rail with vertical supply busbars VX3 - 63A center distance 125 mm Effective protection against overvoltages cannot generally be assured with a single SPD if its protection level (Up) is greater than 1.2 kV (EN/IEC 62305 and TS/IEC 61643-12). When there are overvoltages, an SPD protects equipment by limiting these overvoltages to values that can be tolerated by the equipment. Thus, depending on its discharge capacity (discharge current In, Imax, etc.) and its protection...

Self-protected surge protective devices Consists of ensuring that any downstream SPD (in distribution enclosures or proximity SPDs) is correctly coordinated in energy terms with any SPD located upstream (TS 61643-12). End of life situation involves the exchange of plug-in modules. Always replace all plug-in modules in followings situations : - The indicator on a replacement module has changed to orange. Minimum distances between SPDs (m) * LPS : Lightning Protection System - The integrated circuit breaker has worked and does not reset while plug-in module lights are green. - The upstream differential...
