## Specifications

Surge Buster · SURGE-BUSTER

The Surge Buster is a lightning protection module for the AERL CoolPro cathodic converter. Its twenty-six 4.5 kA metal oxide varistors (MOVs) give common-mode and differential surge protection on the CoolPro’s input, output and local cabinet earth, with a rated output capability of 50 kA (8/20 µs). It also protects the interrupt control and reference cell connections.

**When it is required** The Surge Buster is required only in lightning-prone applications: pipelines or structures longer than 100 metres or higher than 10 metres. There, install the CoolPro with an AERL Surge Buster to supplement its on-board surge protection; lightning damage to a CoolPro installed in such an application without one is not covered by the warranty. Elsewhere the Surge Buster is optional.
