GE THFP365 - 400 A, 600 V, 3-Pole Fusible Panelboard Switch | AmpState

Meet the GE THFP365 Fusible Panelboard Switch—a purpose-built solution for reliable three‑phase power distribution within GE panelboards. Rated at 400 A and 600 V in a 3‑pole configuration, this switch delivers decisive isolation and fuse-based protection, enabling safer maintenance, smooth upgrades, and uninterrupted operation of demanding industrial electrical systems.

High-current, three-pole isolation for safe maintenance

The THFP365 is engineered for heavy load profiles common in manufacturing floors, data centers, and large facilities. Its three-pole design ensures the simultaneous disconnection of all three phases, minimizing arc exposure and providing clean, predictable shutdowns during servicing. This means quicker maintenance windows, fewer surprises during restoration, and enhanced overall safety for your technicians.

Direct compatibility with GE panelboards

Designed to integrate seamlessly into GE distribution architectures, the THFP365 preserves panel layout discipline and wiring cleanliness. This isn’t a generic add-on—it’s a purpose-made component that maintains electrical architecture consistency across your facility, reducing installation guesswork and post-install adjustments.

Fusible protection with sectionalized fault handling

Built‑in fusible switching adds an extra layer of line protection inside the panelboard assembly. By providing contained fault handling and clear sectional isolation, the THFP365 helps manage outages within a defined portion of the distribution network, supporting safer shutdowns and controlled power restoration when issues arise.

Ideal use scenarios

• New installations requiring a robust, replaceable fusible disconnect inside a GE panelboard
• Service upgrades or upgrades within GE-powered electrical rooms needing reliable three‑phase isolation
• Maintenance zones where quick, coordinated power disconnection minimizes downtime across all three phases
