KZY2-C40 2P AC 275V 385V 20KA-40KA Lightning Arrester Surge Protector SPD with PE Household Safety Electrical Protector

The KZY2-C40 2P Surge Protective Device is a robust and reliable solution for safeguarding your household electrical systems against lightning strikes and transient voltage surges. Designed for single-phase 2-pole power distribution, this compact modular unit supports dual operating voltages of both 275V AC and 385V AC, making it versatile for a wide range of residential and light commercial applications. With an impressive maximum surge current capacity of 40kA (8/20μs) and a nominal discharge current of 20kA, it delivers powerful overvoltage defense when you need it most. The voltage protection level is rated at ≤1.5kV, ensuring sensitive equipment stays safe during surge events. The built-in PE connection terminal adds an extra layer of household electrical safety, while the IP20 protection rating and compatibility with both 50Hz and 60Hz systems make it suitable for various installations. A convenient color-coded status indicator window lets you quickly assess the device's operational condition at a glance — green means it's functioning properly, while red signals that replacement is needed. Compliant with IEC61643-11 Type 2 standards, this SPD installs easily on standard DIN rail systems.
