Our featured products automatic transfer switch, circuit breaker, contactor, pilot light,relay, SPD, etc. with solid quality and considerable price and could equip them with enclosure. Surge Protection Device (SPD) It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component. SPD for Power Supply System Series Selection Guide The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity. The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose. SPD for power supply system specification selection principle Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage. TT System: Uc 1.55Uo (Uo is low voltage system to null line voltage) TN System: Uc 1.15Uo IT System: Uc 1.15Uo(Uo is low voltage system to line voltage) Voltage Protection Level: less than the insulation withstand impulse voltage of protected equipment Rated discharge current: determined as per to the lightning situation of the position installed and lightning protection zone.
