Use cases and installation insights

In a multi-panel configuration, the GE SGHA36AT0400 serves as a robust protection point for large feeders feeding downstream subpanels or equipment. Its 3-pole design is ideal for 3-phase systems common in light industrial and commercial spaces, reducing the risk of cross-phase faults and ensuring coordinated protection across the distribution network. The bolt-on mount provides a secure connection to the panel bus, helping minimize maintenance and downtime caused by loose connections.

Practical tips for optimal performance:

• Prefer panelboards that are designed for GE bolt-on MCCBs to ensure seamless fit and wiring compatibility.
• Follow the panel manufacturer’s torque specifications for mounting bolts to maintain a solid bus connection.
• Coordinate protections upstream and downstream to achieve the desired protection scheme and selectivity for your installation.
