Type 1 surge arrester CSH1-100N

class Itelecommunicationsmonobloc

CSH is the most robust range of single pole Type 1/Class I lightning current arresters, able to discharge energy (current) from a direct lightning strike (10/350) on an external lightning protection system (LPS) or overhead supplies. DIN rail monobloc format. Features • Discharges impulse currents with a 10/350 μs waveform: 25 and 100kA per phase. • Follow current quenching capacity. Ifi: 50 kA. • Single pole devices for TNS, TNC, TT and isolated IT earthing systems. • Leakage current free (LCF). • Multidischarge technology. • Suitable as a first step of protection in incoming power supply panels and in areas of high atmospheric exposure. Standards and certifications • IEC 61643-11 • EN 61643-11 Applications • Building • E-Mobility - EV charging • Industry • Telecom • Water treatment
