Surge Arrester (with OBO's new base)

  

Application principle

Surge arrester LY1-C40 series 

- High discharge capacity thanks to powerful zinc oxide varistors / spark gaps

- Low protection level, quick response

- Reliable control thanks to Thermo Dynamic Control disconnector with dual monitoring

- Fault indication by red mark in the inspection window

- Slim design (modular construction) according to DIN 43880

- Multifunctional terminals for connecting conductors and busbars

- Encapsulated, non-extinguishing zinc oxide varistor arrester for use in distributor housings

- Complete prewired unit for common system configurations, consisting of a base part and plug-in protection modules

- Plug-in arrester with dynamic separating device

- Application: Equipotential bonding (LPZ 1 to 2) and device protection in main and sub-distributors
