Overview

The ABB K655ESA-12 Shielded Elbow Surge Arrester provides critical overvoltage protection for medium-voltage systems. Rated for 15/25kV applications with a continuous current capacity of 600 Amps, this device features a Maximum Continuous Operating Voltage (MCOV) of 10.2 kV RMS. The arrester also passes a duty cycle test of 22 operations at 5kA crest while energized at rated voltage for 20 operations and MCOV for the final two. This fully shielded, fully submersible MOV (Metal Oxide Varistor) arrester connects directly with other 600A loadbreak or deadbreak components per ANSI/IEEE 386 standards. Its elbow configuration enables installation in confined spaces and existing cabinetry, reducing retrofit costs. Typical applications include protecting transformers, cables, and underground power distribution systems from lightning and switching surges. Proper placement at radial system ends or loop system open points minimizes damaging surge voltages by improving protective margins. Additional arresters can be strategically installed upstream for enhanced protection.
