The HS1 Type 1+2 AC Surge Protective Device delivers combined lightning and surge protection for low‑voltage AC systems. With an impulse discharge current (Iimp) of 12.5kA (10/350µs), a maximum discharge current (Imax) of 50kA (8/20µs), and a rapid response time ≤25ns, it is engineered for high‑exposure environments. Compliant with IEC 61643‑11 and available in five flexible pole configurations (2+0, 3+0, 4+0, 1+1, 3+1).
