Product Description
SP1-D Class III Surge Protective Device, Power Supply SPD

1.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.
 
2.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.
 
SP1 Series
 
Normal Working Conditions
-Altitude not exceed 2000m
-Ambient air temperature:
Normal range: -5ºC~+40ºC
Extend range: -40ºC~+80ºC
-Relative Humidity: 30% - 90% under indoor temperature condition
- At the place without obviously shaking and shock vibration
- Non-explosion danger medium, non-corrosion gas and dust ( including conductive dust) 
 
Classification
 
-As per Nominal Discharge Current: 
5,10,20,30,40,60KA(8/20µs)
- As per Maximum continuous operating voltage: 
275V,320V,385V,420V,440V,460V
- As per to poles
1P,1P+N,2P,3P,3P+N,4P
- As per auxiliary functions:
a. With remote signal output ( remote alarm function)
b. Without remote signal output
 
Selection Principle
 
- The continuous applied voltage on the two terminals of SPD should not more than the maximum continuous operating voltage Uc value;
- The voltage protection level Up of SPD should less than the maximum impulse withstand voltage of the protected equipment;
- As per to the different earthing system and protection mode to select the specification accordingly;

SP1-D (Class III Protection)

 
Application
 
SP1-D series SPD is suitable for TT,IT,TN-S,TN-C-S power supply system with AC 50/60Hz,230/400V and below. Its design based on IEC6143-1, GB18802.1 and GB50057 standard requirements, can discharge 20KA lightning over current,normally installed at the incoming low voltage distribution board of buildings.
D type lightning current SPD used as equipotential connection during lightning, installed at junction area of LPZ1, LPZ2 and LPZn zone, normally installed at the front of distribution box of residence, computer center, information equipment, electronic equipment and control equipment or in the nearest socket box.
