Polymeric Surge Arrester & Disconnector
PCA Polymeric surge arresters provides active over-voltage protection that contributes directly to improved reliability of the system, reduces outages and protects expensive terminal equipment.
PCA silicone surge arresters are designed and tested to meet customer demands with reliability in offering optimum operational performance.
Proven moisture sealing technology
Non-tracking insulating silicone materials
Fully integrated single piece and void free design
Safe mode of failure
Description
The PCA series of arresters are designed to perform in the toughest environmental conditions to meet and exceed the requirements of IEC60099-4. Our gapless zinc oxide polymeric arresters have been in service since 1986 and the PCA range builds on that experience.
