EXCOUNT-A records the number of significant surges through the arrester.
For gapless surge arresters, surge counters are used only to obtain information regarding surge activities in the corresponding surge arrester and its location. Surge counter, EXCOUNT-A is designed therefore, to withstand the same severe conditions as the arresters without failure.
Advantages
- Highest personnel safety.
- Same performance as ABB arresters.
- Explosion-proof for short-circuit currents up to 80 kA.
- Negligible residual voltage.
- Does not reduce protection margins.
- Reduces risk against accidental contact during surges.
- Long life.
- Molded components, non-sensitive to humidity or temperature variations.
- Verified by tests per IEC 60068.
EXCOUNT-A is suitable for all makes and types of surge arresters.
