T1 Surge Protector 25KA 4P Surge Protection Device Product installation instructions:
• 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.

Types of SPD and Its Mounting Location. Type 1 SPD: Provide lightning protection against transient overvoltage instigates from direct lightning strokes where the lightning discharge voltage could spread from one of the structures earth conductor to the other network conductors. Type 1 SPD is characterized by a 10/350μs surge current waveform per IEC 61643-11:2012
SPD Type 1+2 Surge arrester range for fast busbar mounting in three phase system.
SPD Selection Guide
The SPD selection must be done according to the system network where the sensitive equipment is connected and the level of protection required. Then, different systems AC /DC powerlines, Data lines of specific applications need to use dedicated SPD conceptions to guarantee the right protection.
