Product Overview

The COMPAQ CPSA Series – Polymer Surge Arrestors are precision-engineered to safeguard medium voltage networks and essential electrical assets, including transformers and switchgear, from the damaging effects of lightning strikes and switching surges. Designed for systems up to 36 kV, these arrestors utilise advanced zinc oxide (ZnO) varistor technology, ensuring rapid and effective overvoltage suppression.

The direct-moulded hydrophobic silicone housing offers outstanding resistance to UV, ozone, and surface contamination, enabling reliable long-term performance in challenging indoor and outdoor conditions. Manufactured in ISO 9001 and ISO 14001 certified facilities, CPSA arrestors are fully compliant with IEC 60099-4 standards, ensuring proven quality and safety in global applications.
