Type Selection
DSB5 2 X A 275 N
DSB52 series of overvolt- age surge protection devices is suitable for the protection of AC mains connected devices from the effects of indirect lightning discharges and induced voltages and is intended to provide pro- tection in zones 1 - 2 per IEC 62305. The modules consist in either an high performance Varistor
(MOV) block with thermal disconnection device or an encapsulated air gap device (GDT) which is used as a galvanic sepa- ration between N and PE conductors. Plug in mod- ules facilitate replace- ment of failed modules on site without the need of replacing and rewiring the whole block.
