Tomzn TZG40-PV SPD DC Surge Protector 40KA 1000V

Tomzn TZG40-PV SPD Features and DC Protection Specifications

The Tomzn TZG40-PV SPD combines advanced surge current capacity with compact DIN-rail design, delivering 40KA peak discharge capability that protects solar inverters, charge controllers, and sensitive automation equipment from transient overvoltages. Multi-voltage design eliminates compatibility guesswork: this single arrester works across 500V, 800V, and 1000V DC systems commonly found in residential and commercial solar installations. Metal oxide varistor technology responds in nanoseconds to voltage spikes, clamping dangerous surges before they reach downstream components. The low-voltage arrester construction uses premium ceramic materials rated for thermal stability across industrial temperature ranges from minus 25 to plus 70 degrees Celsius. DIN-rail mounting takes seconds without special tools, and the compact form factor saves valuable panel space in crowded electrical cabinets.
