| Područje primjene (EN): | IEC 61643-01: 2024 contains the common requirements for all SPDs. This document is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages, hereafter referred to as Surge Protective Devices (SPDs). SPDs are intended to be connected to circuits or equipment rated up to 1 000 V AC (RMS) or 1 500 V DC. Performance and safety requirements, tests and ratings are specified in this document. SPDs contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents. This document, together with IEC 61643-11:— (second edition), cancels and replaces the first edition of IEC 61643-11 published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the first edition of IEC 61643-11: a) Clarification on test application either to a complete SPD, to a mode of protection, or to a complete SPD assembly; b) Additional measurement of voltage protection level on combined modes of protection between live conductors and PE (see new Annex F); c) Additional duty test for T1 SPD and T2 SPD with follow current to check for increased follow current at lower impulse current amplitude (see 9.3.5.5); d) Modified and amended short circuit current test requirements to better cover up-to-date internal SPD disconnector technologies (see 9.3.6.3); e) Improved dielectric test requirements for the SPD’s main circuits and added dielectric test requirements for electrically separated circuits (see 9.3.7 and 9.3.8); f) Additional clearance requirements for electrically separated circuits (see 9.4.4); g) Additional information and details for SPDs for DC installations. |
