RSP1 Surge Protector Series Overview
The RSP1-B, C, D series high current modular RSP1 surge protectors are designed for TT, IT, TN-S, TN-C, and TN-C-S power supply systems with AC 50/60Hz, rated voltage up to 380V. They protect the electrical network from lightning strikes or surge overvoltage. The design complies with standards such as C61643-1 and GB18802-2002. These protectors can discharge up to 100KA lightning current, with a shell designed for installation on a 35mm electrical rail. The disconnection device automatically disconnects the protector from the power network, and the status indicator window changes from green (normal) to red (fault). The RSP1 surge protector offers common-mode (MC) and differential-mode (MD) protection methods.
The RSP1 surge protector meets the requirements of GB18802.1, IEC61643-1, and other relevant standards.
Function of Surge Protector
The RSP1 surge protector uses a nonlinear varistor with excellent characteristics. Under normal conditions, the surge protector remains in a state of very high resistance, with almost zero leakage current, ensuring the normal operation of the power supply system. When overvoltage occurs in the power system, the surge protector quickly conducts in the nanosecond range, limiting the voltage to a safe level for the equipment. It then releases the overvoltage energy. Afterward, the surge protector rapidly returns to a high-resistance state, ensuring no impact on the normal power supply of the system.

Why Use Surge Protectors?
Lightning has a tremendous destructive force, and relying solely on external lightning protection (such as lightning rods) is insufficient. Lightning waves can directly or indirectly (through electromagnetic induction) enter electrical paths and metal channels (such as power lines, signal lines, antenna cables, and metal pipelines). The resulting lightning overvoltage and surge voltage can cause significant damage to electronic, electrical equipment, and information network systems. At best, it can damage circuits; at worst, it can destroy equipment, paralyze systems, and cause immeasurable losses. The rapidly changing lightning current induces high voltage on electrical loops and dual-conductor lines, leading to the breakdown of system insulation. Various operations in the power system can generate overvoltage on power lines; certain electrical equipment switch operations or circuit breaker tripping can create overvoltage (surge voltage) in power lines, which can damage electrical equipment.
