Product Description

Advanced AC Power Supply Defense with CAU4-T2-20

Introducing the CAU4-T2-20 Type 2 modular Surge Protection Device (SPD), an invaluable asset designed with a maximum discharge capacity of 20kA. This SPD is essential for the protection of equipment tethered to low voltage AC power supplies, providing a robust shield against transient overvoltages. Whether disturbances are caused by local lightning strikes or the complex switching of inductive or capacitive loads, this device is tuned to deliver unparalleled protection.

Innovative Design for Optimal Safety Compliance

The CAU4-T2-20 features meticulously engineered N-PE and L-N modules, which are integral to preventing the misuse of SPD modules and ensuring device and system safety. Crafted in strict adherence to section 7.3.1 of the IEC61643-11 standard, the device's design helps sidestep potential malfunctions and dangerous scenarios. For example, it avoids the risks associated with inserting the N-PE module's gas discharge tube into the L-N module containing a varistor, an error which could lead to significant hazards such as fires.
