CSH 25

Power Line SPDs - DIN RAIL - IEC TYPE 1

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.
