Surge Suppressor is used to protect electrical equipment from lightning strikes or operational overvoltages.Class T1 (Type I): direct lightning protection, with an inrush current Iimp≥12.5kA (10/350μs waveform), applicable to the inlet end of the main distribution cabinet.Class T2 (Type II): induced lightning protection, with a nominal discharge current In≥40kA (8/20μs waveform), applicable to the sub-distribution cabinet.
Surge Suppressor operating temperature -40℃~+85℃, protection class IP20/IP65 (outdoor type), leakage current <20μA.
Surge suppressor is a high-tech product designed for “surge protection online monitoring”, 35mm DIN-rail installation design, which combines SPD and detection modules together, for on-line monitoring SPD degradation, circuit breaker working status, SPD action times (surge counting). It is realized on-line checking automatically, real-time monitoring.
