Taxnele DC SPD 2P 600V 40kA – Surge Arrester for Photovoltaic Systems

Protects Against Lightning & Switching Surges | 40kA Max Discharge Current, IEC 61643-11

This DC surge protective device (SPD) of the "Type 2" category is a critical element for protecting your photovoltaic (PV) system from the destructive effects of surges caused by lightning or switching events in the grid. It is installed in the distribution board immediately after the main circuit breaker and provides reliable protection for expensive equipment such as inverters and charge controllers.

Key Features & Purpose:

• High Performance & Fast Response: Designed for systems with DC voltage up to 600V. It can safely divert surge currents with a maximum peak capacity of 40KA (nominal 20KA) with an extremely fast response time of less than 25 nanoseconds.

• Effective Protection: Limits the surge to a equipment-safe voltage level of 3.2KV, preventing damage.

• Standardized & Easy to Install: Manufactured in accordance with the international standard IEC61643-11. Its design allows for easy mounting on a standard 35mm wide DIN rail in a distribution board. Protection class IP20.

• Key for Solar Safety: An indispensable component for any serious photovoltaic installation. It is the first line of defense that extends the system's lifespan and protects your investment.
