Surge Protection
Type 2 Fine Protection

Type 2 Fine Protection Surge Arresters are specifically designed to enhance the performance of the Type 2 Medium Protection Devices. When Type 2 Medium & Type 2 Fine Protection Devices are used in cascade, the residual voltage is reduced to 800V or below. This is generally accepted as the safe limit for computer equipment & other sensitive electronic equipment.

Type 2 Fine Protection Devices have low to medium diverting capacity and have exceptionally fast response times (<25ns).

Characteristics

  • Max. discharge current (8/20 µs), Imax – 8kA.
  • Tested with a 8/20 µs waveform (Class II test) which simulates the current produced in the event of a transient overvoltage on the distribution line or its vicinity, according to IEC 62305-4 and AS 1768.
  • Employs metal oxide varistor (MOV) technology.
  • Base element and plug-in cartridge. The replacement cartridges allow simple replacement without the need to cut-off the power supply.
  • Visual indication (red) when replacement of the cartridge is required.
