General Electrics SGHB36BA0400 - 400 A, 3-Pole Bolt-On Circuit Breaker | AmpState

The General Electric SGHB36BA0400 delivers rugged, dependable protection for branch circuits in panelboards and load centers. This 3-pole, 400 A molded case circuit breaker combines a bolt-on mounting design with a thermal-magnetic trip system to handle heavy loads and fault conditions with confidence.

• Secure bolt-on mounting: Provides a rigid, vibration-resistant bus connection that stays tight through equipment start-ups and varying loads, minimizing arcing risks and connection looseness.
• Thermal-magnetic protection: The dual-stage trip unit uses a thermal element for continuous overcurrent sensing and a magnetic element for immediate response to high-energy faults, ensuring stable and repeatable protection performance.
• 3-pole configuration: Ideal for three-phase systems common in commercial and light industrial settings, with a robust 400 A rating to handle substantial loads and inrush currents.
• OEM-compatible: Designed to pair with matching General Electric OEM load centers and panelboards, facilitating straightforward replacement and consistent performance across your electrical distribution system.
• Versatile application: Suitable for residential, commercial, and light industrial environments where reliable overcurrent and short-circuit protection is essential.

Why this bolt-on MCCB stands out

Unlike plug-in breakers, the bolt-on configuration of the SGHB36BA0400 anchors the breaker securely to the bus, reducing movement and wear in panels subject to vibration or heavy equipment cycling. Its thermal-magnetic trip unit provides a clear, predictable trip curve, helping electricians diagnose nuisance trips and ensure fast, safe responses to genuine faults.

Ideal use cases

• Main distribution panels in multifamily or commercial buildings where dependable protection of large branch circuits is critical.
• Load centers in light industrial facilities powering motors, compressors, and conveyor systems that generate substantial inrush currents.
• Retrofit or upgrade projects needing a compatible, high-current breaker that aligns with existing OEM panelboard standards.
