International Standards
The phenomena were first characterized and a series of standardized waves created (1.2/50µs voltage wave and 8/20µs and 10/350µs current waveforms), then a number of standards defining surge arrester performance were issued, among them : Surge Protectors for Low-Voltage installations: - NF EN 61643-11 (France) - VDE 0675-6-11 (Germany) - EN 61643-11 (Europe) - UL1449 (USA) - IEC 61643-11 (International) Surge Protectors for Telecom equipment: - IEC 61643-21 (International) - ITU-T recommendations K11, K12, K17, K20, K21, K36 (International) - UL 497 A/B (USA)
Citel, CTC Technology
This game-changing technology brings a number of benefits for you: - Space saving due to more compact design - Short conductor lengths between MOV and cut-off device - Fast triggering of the cut-off by cumulative heat impact of all MOVs on one heat point - Additional insulation barrier for even safer pole separation - All-pole disconnection in case of tripping - No risk of varistor short circuits - Much lower temperature of the SPD envelope during disconnection providing more safety - For the user or side by side electrical devices C T C® "CENTRAL“ - The central position of the disconnection device "THERMAL“ – More efficient use of Joule-heat for more safety "CONTROL“ – All-pole disconnection with dual mechanism | --- | |

GDT overview
Nevertheless, it is prudent to plan for the worst case scenario and, for this reason, CITEL has designed a model SPT203 allow to test statut of GDTs and surge protector STANDARDS CITEL GDT comply with the specifications of main telecom operators and with the ITU-T K12 international recommendation and standards IEC 61643-311 They are also compliant with the RoHS directive
