SGHA26AT0400 - 400Amp Max. *Frame Only*

When you're maintaining or repairing an existing SG600 line electrical distribution system, finding the right replacement components matters. The SGHA26AT0400 is a 2-pole, 400-amp industrial molded case circuit breaker frame designed for applications that use a compatible electronic trip system. Because this is a frame only, it's intended for installations where the appropriate electronic trip components are already being used or will be installed separately. Designed as a form, fit, and functional replacement, the SGHA26AT0400 helps keep existing electrical systems operating without requiring unnecessary modifications. Its current-limiting design and interrupting ratings of 35kA at 480VAC and 65kA at 240VAC make it suitable for a wide range of industrial and commercial power distribution applications. Built for long-term service, this breaker frame is commonly used in facilities where dependable circuit protection and equipment compatibility are essential. Whether you're replacing a damaged breaker frame during scheduled maintenance or sourcing a compatible component for an existing installation, the SGHA26AT0400 provides the ratings and configuration needed for many legacy electrical systems.
