8/20 μs

8/20 Current Impulse

Current impulse with a nominal virtual front time of 8 µs and a nominal time to half-value of 20 µs. 

— (IEC 61643-11)

1.2/50 μs

1.2/50 Voltage Impulse

Voltage impulse with a nominal virtual front time of 1.2 µs and a nominal time to half-value of 50 µs.  

— (IEC 61643-11)

U_c

Maximum Continuous Operating Voltage

Maximum r.m.s. voltage, which may be continuously applied to the SPD's mode of protection. 

— (IEC 61643-11)

I_n

Nominal Discharge Current

Crest value of the current through the SPD having a current waveshape of 8/20.

Modes of protection

An intended current path, between terminals that contains protective components, e.g. line-to-line, line-to-earth, line-to-neutral, neutral-to-earth. 

— (IEC 61643-11)

IP

Degrees of Protection Provided by Enclosure (IP Code)

Classification preceded by the symbol IP indicating the extent of protection provided by an enclosure against access to hazardous parts, against ingress of solid foreign objects and possibly harmful ingress of water.

Usage

1. Frequency range is from 47 Hz to 63 Hz.

2. The voltage applied continuously to the SPD must not exceed its maximum continuous operating voltage Uc.

3. When atmosphere press is from 80 kPa to 106 kPa, the related altitude shall be from 2000 m to - 500 m.

4. Do not touch the product body or wires directly when power is on, to avoid electric shock.

Replacement

 As SPD is a non-repairable product, for safety sake, please use the same type of SPD for replacement.

 Storage

 Do not store SPD at high temperature, high humidity or corrosive gas environment, to avoid oxidation of the wires. Use them up within 1 year after receiving the goods.

 Installation  

1.   Installation and startup may only be carried out by qualified personnel. The relevant country-specific regulations must be observed.

2.   Check the device for external damage before installation. If the device is defective, it must not be used.

3.   Pay attention to risk of electric shock. Please cutoff all electrical power before installation or service.

4.   Lay the output cables to the surge protective devices (SPDs) as short as possible, without loops.

5.   Please install proper backup protection devices in front of SPD.

6.   Do not apply mechanical stress to the SPD body during or after the installation.

Maintenance

1.   Check SPD status according to instructions before and after the thunderstorm season each year.

2.   If the indicator of "failure state" appears, the SPD is damaged. Replace the SPD with same type.

3.   Ensure electrical connections and mountings are correct before energizing the circuit.

4.   SPD`s quality is well controlled and strictly inspected before delivery. If non-functional ones are found during operation, please contact us early enough.
