Overview

IDUSCB backup protectors are suitable for use in TT, TN-S, TN-C, IT, TN-C-S, and other power supply systems under AC 50/60Hz, 380V, and for surge protection against lightning strikes or other transient overvoltages.

IDUSCB complies with GB/T18802.1/IEC61643-Ⅱ

Scope of use

◆ Selective breaking of the passing ⼯ frequency current and lightning current can effectively protect SPD from melting through and short circuit due to abnormal transient over-voltage, resulting in serious disasters.

◆ The selective disconnection of the passing ⼯ frequency current and lightning can effectively protect SPD from serious disasters due to the deterioration of the starting voltage of SPD which is lower than the power supply voltage ⼯ frequency leakage current increases ⼤.

◆ When SPD has lightning current, this external device will not trip by mistake, so that the lightning protection of electrical equipment is always effective.

Product Features

◆ Parametric control tripping mechanism to realize selective breaking of current passing through

◆ The residual voltage of impulse current is low, and the withstand energy is low

◆ High energy contact, long service life

◆ Modular module, with a volume of ⼩, can be installed with SPD

◆ Full specifications, fully equipped with T1, T2, T3 SPD at all levels

◆ 35mm guide rail installation meets the installation requirements
