metal-oxide low voltage arrester/ surge protective device/LVA-280B

Low voltage surge arresters provide protection for low-voltage overhead lines, consumer in-house supplies, distribution transformers and other systems. The gapless metal-oxide varistor incorporated in the surge arrester reliably imposes low-value limits on surges caused by atmospheric over voltages and switching transients, thus protecting the insulation of the consumer-side networks and equipment.
