The P series is a power-type surge protective device (SPD) designed in accordance with IEC, GB and other standards. At the instant a surge occurs, it connects the protected circuit into an equipotential system and limits the voltage to a certain level, thereby protecting the user's electrical equipment.<\/p>\n
SPDs are mainly used to protect field devices such as transmitters, switches, frequency signals, communication equipment, RTDs and thermocouples connected in two-wire or three-wire configurations, as well as equipment in the control room such as safety barriers, I\/O, DCS and PLC, from damage caused by lightning surge impulse voltages or switching overvoltages. The P series includes DC power SPD models, and the protection module supports hot swapping.<\/p>","protected":false},"excerpt":{"rendered":"
