Overvoltage products Main power supplies
Transient overvoltages Modular cabinets - VE range - 120/208 V and 230/400 V~ networks Surge protective devices guideline (1)
The installation of the surge protective devices should be done in compliance with the electrical safety rules of the electrical standards NF C 15-100, IEC 60364 or all equivalent electrical standard in the country. As for all electrical equipments, their installation should be done according to the electrical safety rules, for the protection of the persons and equipments, against the risks of faults of the network and the directs or indirect contacts, coordination and of selectivity of the protection devices for the protection against the heating and fires risks, types of protection devices specified in the technical sheets of the SPD `s.

TT system: Recommendations for the electrical safety
A protection type "C1" ("4+0" or "2+0") will be obligatorily installed downstream from the differential circuit breaker (RCD) of the board in which is integrated in order to ensure the protection against the indirect contacts (currents of defects). A protection type "C2" ("3+1" or "1+1") will be installed as well upstream as downstream from the differential circuit breaker of the board. 1 Independently of the risk assessment, a protection type 1 with limp = 12.5 kA min. (class I of tests, EN 61643-11) is compulsory at the input of a protected building, (or belonging to a protected site) against the direct impact of the lightning (lightning conductor...). 2 Protections recommended for important industrial sites and sensitive sites. 3 Protections recommended when the equipment to protect are distant more than 30 m from the upstream protection (effects of lines which can provoke overvoltages superior to the residual tension of the surge protective device). 4 Optional. Protections recommended if the continuity of service is required or in presence of sensitive equipment. 5 2+0, 3+0, or 4+0 (type "C1"): protection L-PE and N-PE (connection of type 1) 3+1 or 1+1 (type "C2"): protection L-N and N-PE (connection type 2). L: line N: neutral PE: earth.
