APU5-T2 DC Surge Protective Device(SPD) is suitable for AC 50/60Hz distribution and control systems with a rated voltage of single-phase 230V/ three-phase 400V. It meets the level II test requirements for surge protectors (SPD) and is used to suppress transient overvoltage below the equipment's withstand overvoltage, discharge surge energy, and thereby protect system circuits and equipment.
Surge protectors quickly divert surge voltages or currents in an electrical system to ground, preventing these voltages or currents from flowing through equipment and thus protecting it from damage.
Effectively limit overvoltages and discharge surge currents, ensuring the safety of electronic equipment.
By reducing surge voltages in an electrical system, surge protectors improve system stability and reliability, reducing the occurrence of system failures.
It provides safety protection for various electronic devices, instruments, and communication lines.
