SPA102 Datasheet (Click here to open)

The SPA102 is a type 2/3 surge arrester, suitable for use at the boundary of LPZ 1-2.

This surge protection device provides an economical means of preventing damage to electrical installations from induced voltage transients caused by switching or nearby lightning strikes.

The SPA102 provides three mode system protection from mainsborne voltage spikes and surges that can occur between phase and neutral, phase and earth, neutral and earth and additionally phase to phase for the three phase model.

This protection is achieved by using high energy elements which absorb or redirect incoming mainsborne transients. This unit has two stages of protection, the status of which is clearly indicated by lights incorporated in the front panel, thus ensuring continuity of protection by allowing time for replacement once the first stage has ceased to protect.

  • Type 2 – Class 2 & Type 3 – Class 3
  • Voltage Rating (Nominal) – 230V rms
  • Maximum Operating Voltage – 300V rms
  • Maximum Current Rating – Unlimited (Parallel Connection)
  • Leakage Current – 0.15mA
  • Maximum Surge Current Handling (8/20 μs) – 10 kA
  • Response Time – < 10 ns

This surge protection device can only be purchased as a unit on its own.
