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 provides robust protection against overvoltage and transient voltage surges, safeguarding sensitive equipment. 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 a high discharge capacity, fast response time, DIN rail mounting, double thermal disconnection for enhanced reliability, and a visual status indicator (green for normal, red for defect requiring module replacement). The NPE model incorporates a discharge tube between the N and PE sections. Customization options such as remote signaling interfaces are available upon request.
