Why this GE breaker stands out

Unlike plug-on variants, the bolt-on design of the SGDA36AN0400 delivers a more robust mechanical connection, reducing the risk of loose bus bars in environments with vibration or long-term operation. The thermal-magnetic trip unit ensures reliable protection across a range of fault scenarios, offering predictable response times that help prevent insulation damage and electrical fires. Because this unit is engineered to pair with GE OEM load centers, you get measured trip curves and physical compatibility that streamline installation and ongoing maintenance.

Ideal use cases

• High-demand residential subpanels where large branch circuits require solid, code-compliant protection
• Commercial distribution panels that demand dependable overcurrent and short-circuit protection for critical equipment
• Light industrial panels in areas with vibrations or frequent equipment start-ups, where a sturdy bolt-on connection improves long-term reliability
• Retrofit or upgrade projects within GE-aligned panel ecosystems to maintain continuity of protection and compatibility

Installation and compatibility tips

To maximize safety and performance, ensure the panelboard or load center is compatible with GE SGDA36AN0400, and follow the manufacturer’s installation instructions for bolt-on mounting. Verify the mounting footprint and bus connection alignment with the enclosure, and use the recommended torque and fastening procedures to maintain a secure, vibration-resilient connection. This breaker is designed to seamlessly integrate into GE’s matching OEM environments, helping you maintain coordinated protection across your distribution system.

With the GE SGDA36AN0400, you get a purpose-built, reliable solution for safeguarding large-draw circuits and keeping electrical systems running smoothly in homes, businesses, and light industrial settings.
