Surge Arrester Type 1+2, 220V AC, 3P+N, 4 DIN Rail Modules – Ettroit JXSPD-3P+N
The Ettroit JXSPD-3P+N surge arrester is a combined Type 1 and Type 2 device, designed for the protection of three-phase electrical systems with neutral (3P+N) in 220V AC networks.
Main technical features:
SPD Type : Combined T1 + T2 (Class I + II)
Rated operating voltage (Un) : 220V AC
Maximum continuous voltage (Uc) : up to 275V AC for each pole
Rated impulse current (Iimp) : up to 12.5 kA per pole (10/350 µs)
Nominal discharge current (In) : 20 kA (8/20 µs)
Maximum discharge current (Imax) : 40 kA (8/20 µs)
Configuration : 3 Poles + Neutral (3P+N)
Status indicator : integrated (mechanical)
Connection : screw terminals for rigid or flexible conductors
Mounting : standard 35 mm DIN rail – Occupancy: 4 DIN modules
Housing : self-extinguishing, protection degree IP20 (IP40 when the panel is closed)
Rapid response : <25 ns
Applications:
Ideal for main electrical panels in civil, tertiary and industrial environments, it guarantees high discharge capacity in the presence of atmospheric events (direct lightning strikes) and transient switching overvoltages.
