Plug-in surge arrester POLIM-D..PI-2/-3

Plug-in arrester for IEC class distribution high (DH) for AC systems up to 52 kV

Surge arrester with metal-oxide (MO) resistors without spark gaps directly molded with silicone rubber, in a touch-proof metal clad, designed and tested according to IEC 60099-4.

The arrester is applicable for inner cone systems according to DIN EN 50181 and DIN 47637.

The arrester is available in cone sizes 2 and 3. It is used for secure protection of transformer and metal-clad switchgear against overvoltages from atmospheric discharges and switching conditions.
