The 15HK is a high-voltage air circuit breaker designed for electrical protection and switching applications. It features a rated continuous current of up to 1200A or 3000A depending on the model, with impulse KV ratings of 95kV and maximum KV ratings of 15kV. The 15HK series includes models such as 15HK-150, 15HK-250, and 15HK-1000, compatible with various frame sizes including 5HK, 7.5HK, 15HK, and 20HK. These circuit breakers are equipped with arc chutes that require compressed air for maintenance and are suitable for use in electrical systems requiring reliable interruption at high voltages and currents. The 15HK series is manufactured by Gould and is part of the HK product line, known for their robust construction and high-performance capabilities in industrial and utility applications.

Gould, a historic name in industrial automation, was known for its PLCs, control systems, and electrical components. Now integrated into Schneider Electric, its legacy continues through advanced automation and control solutions supporting various industries.
