SURGE PROTECTION

SALTEK, Limited Liability Company, is a Czech company specialized in the development and the 

production of surge protective devices (SPD). We offer a wide assortment of lightning current 

arresters and surge protections protecting electric and electronic equipment in low voltage 

supply mains, a wide range of surge protections for computers, measurement and control and 

telecommunication. All products conform to international standards. 

SALTEK was established in 1995. The company’s headquarters, Management, Production, 

Sales and Development are all based in Ústí nad Labem. Since its establishment, SALTEK has 

achieved very good results and high annual turnover growth and we soon became the Czech 

market leader. The principle of dynamic company expansion lies in our product development, 

using sophisticated materials, design processes, technologies and measuring methods. The 

development area and our laboratory are equipped with unique apparatuses and technologies. 

Exceptional attention is paid to care for product quality. The Quality Control System according 

to ISO 9000 standards was introduced and certified in 1998. In the following year, the company 

implemented the Safety Management System and the Environmental Management System. The 

company is audited by TÜV NORD Czech, s.r.o., a member of the TÜV NORD Gruppe, on a yearly 

basis. 

For a long time, SALTEK has maintained a dominant position on the Czech market of surge 

protections and also a firm position in Europe. Foreign trade activities are secured by our 

subsidiaries, SALTEK TRADE, SALTEK Slovakia and SALTEK RU. 

SALTEK organizes regular training for designers, investors and suppliers, where we present our 

products as well as new trends in the surge protection field. At such training, we introduce our 

partners and clients to our range of surge protections, with the proper method of their design, 

installation and use. 

The SALTEK Company represents itself at professional exhibitions in the Czech Republic and 

abroad. Traditionally, we take part in the most significant Czech trade fair, AMPER, and in the 

professional exhibitions ELOSYS and ELEKTROTECHNIKA Ostrava. Since 2000, SALTEK has 

exhibited at the international Light & Building Fair in Frankfurt upon Mohan and the Hannover 

Messe Fair in Hanover.

Lightning and surge protection 


1. Introduction – Legislative 

The use of modern sophisticated apparatuses, 

equipment, consumer electronics and 

control systems places high demands on 

their electromagnetic compatibility. Modern 

electronic control systems provided with circuits 

with a very high integration level are becoming 

more and more sensitive to electromagnetic 

disturbance and overvoltage. The installation of 

surge protections according to effective legal 

regulations will reduce the danger of their being 

damaged to a minimum. 

Conditions for safe operation and function of 

electrical equipment for the Czech Republic 

are specified in detail in Act 205/2002 and 

Ordinance 18/2003. 

Technical designs are defined by standards 

harmonised with EU standards: 

a) Protective bonding to the same potential 

including the conductor cross section for the 

main and additional bonding is defined by 

standards EN 50 310. 

b) Lightning protection is specified in the 

EN 62 305 collection of new standards, 

harmonised with European standards, 

whereas EN 62 305 – Section 1 deals with 

general principles.

EN 62 305 – Section 2 – deals with the risk 

assessment for buildings or engineering

EN 62 305 – Section 3 – deals with the proposal

Lightning protection zones 

The standard EN 62305-4 (EN 61312-3) defines 

lightning protection zones LPZ in view of the 

direct and indirect (electromagnetic pulse – LEMP) 

lightning effect: 

LPZ 0 A – free area (possibility of a direct 

lightning strike, non-attenuated LEMP) 

LPZ 0 B – lightning conductor receiver 

protection area (direct lightning strike 

protection, non-attenuated LEMP) 

LPZ 1 – inside a building (direct lightning strike 

is eliminated, attenuated LEMP – depending 

upon shielding) 

LPZ 2 – inside a room – e.g. a server room with 

a conductive floor, FeAl floors and wall lining 

(further attenuation of LEMP in connection with 

a higher shielding level) 

LPZ 3 – inside a metal box (e.g. 19“ RACK) 

base ground 

EN 62 305 – Section 4 – deals with protective 

measures resulting in the reduction of failures 

of electric and electronic systems inside the 

building (zone protection) (also in ČSN IEC 61 

312-3). 

c) Classification of protections is set forth in 

standard EN 61 643-11. 

Protections are classified into three basic 

categories: 

SPD type 1 – lightning current arresters 

SPD type 2 – surge protections 

SPD type 3 – surge protections

d) Classification of low-voltage distributions

dimensioned.

4. Principles of positioning and wiring of surge protections and lightning current arresters 

Surge protections and lightning current arresters cannot be installed in the distributor at random. You must be aware of the fact that protection should be 

placed in closest proximity to the input feed cable in the distributor in order to minimize the inductive loop area, see fig. 1. 

Fig. 1 – Examples of protection positioning in the distributor. 

overhead, PEN (PE) down overhead, PEN (PE) up underground, PEN (PE) down underground, PEN (PE) up 

Another important condition for the wiring of protections is to minimize the impedance of interconnecting conductors. Since the fault current flowing 

through the protection has a frequency at which the current does not flow through the whole cross section but pushes towards the conductor surface 

(skin effect), it is necessary to use a stranded conductor or a strip conductor for the wiring of protections. Furthermore, the length of the interconnecting 

conductors must be as short as possible (the total length of interconnecting conductors must not exceed 0.5 m). The cross section of the interconnecting 

conductors should be as large as possible – maximum up to the cross section according to the terminal type. 

The cross section of interconnecting conductors is recommended to be larger by at least one sequence number than the PEN (PE) conductor diameter (e.g. 

if the PEN conductor diameter is 10 mm 2 , the cross section of the interconnecting conductor should be 16 mm 2 ). 

If protections are placed in a circuit fitted with residual current devices (RCD), the protection must be set before the RCD (not in the RCD circuit) to avoid 

spontaneous RCD availability due to surge protections or lightning current arresters. 

If the RC is placed before the protection, it is necessary to use the delayed RCD type, e.g. S-type or G-type.

with suppressed leakage current 


Efficient varistor connected in series with an encapsulated spark gap. To be 

installed in IT and TT networks, networks with a motor generator backup and DC 

supply networks, at the boundary of LPZ 1–LPZ 2 zones and higher. It is designed 

exclusively to prevent the effects of overvoltage induced during lightning strike 

and to prevent switching overvoltage. It does not affect the activity of earthleakage 

relays or the RCD function. The little amount of leakage current does not 

increase for the duration of the service life; protective elements are not subject to 

ageing. Optional remote status signalling (S).
