Product Introduction
The TOMZN TZG40-C N-PE series surge protective device (SPD) is designed for low-voltage AC power systems, complying with IEC/EN 61643-11 standards. It protects power lines and connected equipment from overvoltage and transient surges. Available in 1P+NPE and 3P+NPE configurations with rated AC voltages of 275V or 385V and a discharge current rating of 20-50kA. Key features include high discharge capacity, fast response time, low residual voltage, double thermal disconnection for enhanced safety, and a visual status indicator (green: normal, red: replace module). The NPE model incorporates a discharge tube between N and PE. Optional remote signaling interfaces are available upon request. DIN rail mounting ensures easy installation.
