General Electrics SGHB36BC0400 - 400 A, 3-Pole Bolt-On Circuit Breaker | AmpState

The General Electric SGHB36BC0400 delivers dependable, high-current protection for demanding electrical systems. At 400 amps and three poles, this bolt-on molded case circuit breaker is built to guard panelboards and load centers from overcurrent and short-circuit events with precision and confidence. Designed for residential, commercial, and light industrial environments, it’s a purpose-built solution for serious electrical protection where reliability matters most.

What makes the SGHB36BC0400 stand out?

• Secure bolt-on mounting for a rigid, vibration-resistant bus connection. This minimizes connection looseness and stray trips in installations subject to vibration or movement, such as commercial spaces and utility rooms.
• Thermal-magnetic trip unit delivers stable, repeatable protection. It responds to both overload current and instantaneous short-circuit conditions, helping prevent damage to conductors and downstream equipment while reducing nuisance trips.
• 3-pole configuration supports three-phase circuits, making it ideal for larger feeders, commercial equipment, and motor loads where coordinated protection is essential.
• High-current capability with a 400A rating, enabling robust protection for main feeders and substantial branch circuits without compromising safety or performance.
• OEM-compatible with matching General Electric panelboards/load centers, ensuring seamless physical fit, electrical coordination, and streamlined retrofits or upgrades.

Why this bolt-on breaker matters for your projects

When you’re upgrading an electrical system or expanding capacity, you need protection you can trust. The SGHB36BC0400 is engineered to align with the specific tolerances and bus configurations of compatible General Electric panelboards, reducing installation guesswork and preserving system integrity. Its bolt-on design is particularly advantageous in installations where plug-in breakers aren’t feasible or where a solid, vibration-resistant connection is required to maintain continuity under demanding operating conditions.

Ideal use scenarios

• Upgrading service panels in multi-tenant commercial spaces or light industrial facilities that demand reliable 3-phase protection.
• Installing new feeders for HVAC, pumps, or heavy-duty machinery where a 400A main or large feeder needs robust, coordinated protection.
• Retrofits in residential or commercial panelboards that require a bolt-on, molded case solution to maintain compatibility with OEM equipment.

How it helps you outperform typical solutions

• Compared to smaller, plug-in breakers, the 3-pole bolt-on format provides a physically secure connection, reducing wear and loosening over time in vibration-prone environments.
• The integrated thermal-magnetic trip curve delivers predictable tripping behavior, which simplifies coordination with other protective devices and reduces unexpected outages.
• Being part of the General Electric family, it’s designed to align with OEM designs and panelboard architectures, delivering reliable electrical performance and easier inventory planning for installers and facilities managers.
