Fitur:
Pole number:1P,2P,3P,4P,1+1NPE,3+1NPE
Powerful components, suitable for all kinds of common power systems.
Can be used in TN-S systems
The surge arrester meets the requirements of IEC61643-11
The unit is designed to be used between Zone O and Zone 1 (according to IEC62305-4 definition of Lightning Protection Area).
The product is mainly used for the Class I protection of the power system.
The product is mainly 10/350 waveform, up to 25KA
Installed in the main power distribution
Aplikasi:
• The product is mainly used for primary protection of power system.
• Application-optimised and prewired combined lightning current and surge arrester for TN-S systems.
• Installed in the main power distribution box.
• Used to Industry and automation, commercial and residential installations, telecom & IT & data centers, water treatment, smart grid & LV metering, photovoltaic and wind etc.
Instalasi:
• Power must be cut off before installation. Live operation is prohibited.
• It is recommended that a fuse or circuit breaker be connected in series at the front end of the surge protection.
• SPD is installed in parallel at the power supply inlet end of the building distribution box or the equipment room. The product is installed in the guide rail type. If conditions permit, the Kevin connection mode can be adopted.
• During installation, connect the device according to the installation diagram, where L is the phase line,N is the neutral line, and PE is the ground line. Do not misconnect the device. After the installation is complete, turn on the automatic circuit breaker and check whether the working status is normal.
• When the SPD is in use, check the status of the fault display window regularly. If the fault display window is red or the remote terminal outputs an alarm signal, it indicates that the SPD is faulty and should be repaired or replaced in time.
• Suitable for indoor operation, such as installed in the outdoor, must be equipped with waterproof shell.
