ETU5-T2-60 Series AC Surge Protective Device is designed for surge protection in low-voltage power distribution systems. With Type 2 / Class II protection, in 30kA (8/20μs), and Imax 60kA (8/20μs), it provides reliable protection against lightning-induced surges and switching overvoltages in building and industrial distribution applications.
The product features a keyed N-PE module design and a removable arc-safe barrier to help prevent incorrect replacement while improving installation safety and maintenance convenience. Its appearance and mounting dimensions are consistent with T Series devices, allowing side-by-side installation and a uniform panel layout.
