This Technical Specification was prepared by the Technical Committee CENELEC TC 37A, Low voltage surge protective devices. The text of the draft was submitted to the formal vote and was approved by CENELEC as CLC/TS 50539-12 on 2009-10-30.
This Technical Specification describes the principles for selection, location, coordination and operation of SPDs to be connected to PV installations. The d.c. side is rated up to 1500 V d.c. and the a.c. side, if any, is rated up to 1000 V rms 50 Hz.
The International Electrotechnical Commission (IEC) has released IEC 60364-7-712:2017 for “Low voltage electrical installations – Part 7-712: Requirements for special installations or locations – Solar photovoltaic (PV) power supply systems”.
The newly issued UL 1449 Standard for Surge Protective Devices for safety and is the preferred standard for all AC surge protection devices (SPDs).Requirements that cover surge protective devices (SPDs) designed for the repeated limiting of transient voltage surges as specified in the standard on 50 or 60 Hz power circuits not exceeding 1000 V.

The protective wiring method in which the metal part of the electrical appliance (that is, the metal structural part insulated from the live part) which may be charged after the insulation material is damaged or in other cases is reliably connected by the conductor and the grounding body. The grounding protection system has only phase and neutral lines.
Lightning protection equipment is through modern electricity and other technology to prevent the equipment being struck by lightning. Lightning protection equipment can be divided into power lightning protection, power protection socket, antenna feeder protection, signal lightning protection, lightning protection testing tools, measurement, and control system lightning protection, earth pole protection.
Surge Protection Device SPD is also named arrester, All surge protectors for a specific purpose are actually a kind of rapid switch, and the surge protector is activated within a certain voltage range. After being activated, the suppression component of the surge protector will be disconnected from the high-impedance state, and the L pole will be turned into a low-resistance state.
Power over Ethernet (PoE) Surge Protector model ND-CAT 6A/EA is specifically designed to protect communication devices connected via Ethernet LAN from lightning surge entering through network cables.
The SCB (Surge Circuit Breaker) dedicated backup protector provides professional backup protection for the SPD (Lightning Protection Device) that protects the power supply.
