Overview

The ABB K655ESA-15 ESA Elbow Surge Arrester is a shielded surge protection device engineered for medium-voltage systems operating at 15/25 kV. This 600 A elbow-style arrester delivers reliable overvoltage protection for critical infrastructure, including substations, distribution networks, and industrial facilities. The device features a maximum continuous operating voltage (MCOV) of 12.70 kV RMS, ensuring compatibility with systems where line-to-ground voltage under normal conditions does not exceed this rating. Designed to meet ANSI/IEEE Standard 386 for interface compatibility and IEEE C62.11 for surge arrester performance, the K655ESA-15 provides robust protection against transient surges. Its compact elbow design simplifies installation in tight spaces, reducing maintenance time and operational downtime. The shielded composite construction enhances durability by minimizing exposure to environmental contaminants and physical damage, ensuring long-term reliability in harsh environments. The arrester’s temporary over-voltage (TOV) capability allows brief operation at power-frequency voltages above its MCOV rating, providing added flexibility for transient conditions. Ideal for protecting transformers, switchgear, and other high-voltage equipment, this ABB surge arrester delivers consistent performance and peace of mind in power distribution applications.
