GE SGPP36AT0400 - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE SGPP36AT0400 is a robust 3-pole bolt-on molded-case circuit breaker designed to shield panelboards and load centers from overcurrent and short circuits. With a 400A rating and a 600V maximum, it delivers dependable protection for high-demand feeders and branch circuits in residential, commercial, and light industrial settings.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing loosening risks in equipment subject to vibration and movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element handles overloads for predictable operation, while the magnetic element quickly trips on high-magnitude short circuits.
• Three-pole design ensures synchronized interruption of all phases, preserving balanced protection for 3-phase systems and reducing arc consequences.
• OEM compatibility is designed to fit and function with matching GE OEM load centers and panelboards, simplifying retrofits and upgrades.
• Versatile application ideal for residential service panels, commercial electrical rooms, and light industrial installations needing reliable 400A, 600V protection.

What this means in real terms: you get a high-current main or feeder protection device that trips reliably when faults occur, minimizes downtime, and integrates smoothly with GE’s panel architecture. The bolt-on format is particularly advantageous in retrofit projects or installations where OEM mounting hardware and bus connections are standard, helping ensure a solid electrical connection from the moment you tighten the mounting hardware.
