General Electrics SGHB36BB0400 - 400 A, 3-Pole Bolt-On Circuit Breaker | AmpState

The General Electrics SGHB36BB0400 is a 400 A, 3-pole bolt-on molded case circuit breaker engineered for dependable branch-circuit protection in panelboards and load centers. Built to withstand the demands of busy electrical environments, this breaker delivers reliable overcurrent and short-circuit protection where it’s needed most.

Key advantages that matter in the real world

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing connection wear and maintaining consistent protection even in panels subject to vibration or movement.
• Thermal-magnetic trip unit delivers stable, repeatable protection: the thermal element handles sustained overloads, while the magnetic element responds instantly to high-energy short circuits for rapid disconnection.
• OEM-compatible design is built to work with matching GE OEM load centers and panelboards, supporting straightforward replacements and reliable integration into existing systems.
• Versatile for multiple settings suitable for residential, commercial, and light industrial applications, making it a practical choice for a wide range of panel configurations and protection strategies.

What this means for your installation and daily operation

• When you need a robust feeder protection solution for a 400 A circuit, this 3-pole breaker ensures coordinated protection across phases, helping prevent equipment damage and electrical fires.
• In new builds or panel upgrades, the bolt-on design simplifies mounting and alignment, supporting a solid, long-term bus connection that stands up to routine maintenance and voltage fluctuations.
• For service upgrades or replacements in GE-based ecosystems, the SGHB36BB0400 aligns with GE’s panelboard families, reducing compatibility concerns and easing installation timelines.
