• Electrical rooms and control panels requiring reliable 3-pole protection up to 600 V

Why the 3-pole, 90 A, 600 V configuration matters

The 3-pole design ensures simultaneous interruption of all three phases, reducing the risk of phase imbalances and protecting connected equipment from uneven fault currents. With a 90 A rating, it provides targeted protection for circuits that demand steady, reliable performance without compromising on system availability in busy commercial or light industrial environments. The 600 V rating expands its suitability to higher-voltage distribution tasks, helping you consolidate protection in a single, compatible unit.

Installation and compatibility tips

• Use only in Square D panels that accept HGA-series breakers to ensure proper fit and performance.
• Match the ampere rating and pole count to the intended circuit to maintain intended protection and trip characteristics.
• Label circuits clearly and store a compatible spare in the electrical room for quick maintenance and downtime reduction.
