Surge Protector CITEL AC 3-phase T1+T2 / 571504 / 571514 DS134RS-230

Surge protector DS134RS-230/G is a four-pole surge arrester type 1+2 designed for AC 230V networks, intended as the first level of protection in distribution boards equipped with lightning protection or exposed to strong electromagnetic fields. The device combines three modules with a high-power varistor block and one module with a gas discharge tube type 1 to N/PE.

The manufacturer of the protective element is CITEL, specializing in surge protection; the distributor in the Polish market is JEAN MÜLLER POLSKA Sp. z o.o., based in Warsaw.
