GE SGLA36AI0400 - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE SGLA36AI0400 is a rugged 400A, 600V, 3-pole bolt-on molded case circuit breaker designed to safeguard branch circuits and prevent short-circuit damage in panelboards and load centers. Built for reliability in residential, commercial, and light industrial environments, this unit combines a secure bolt-on mounting with a thermal-magnetic trip system that delivers stable, repeatable protection across varying electrical conditions.

Key features and benefits

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing loosening risk and ensuring long-term reliability in demanding installations.
• Thermal-magnetic trip unit delivers coordinated protection: the thermal element handles overloads with predictable time delay, while the magnetic element responds instantly to short circuits for fast disconnection.
• Molded case design offers robust enclosure protection for internal components, enhancing longevity in panel environments.
• OEM load center compatibility is engineered to align with GE panelboards and loadcenters, supporting proper fit, performance, and warranty integrity.
• Three-pole configuration is ideal for three-phase systems, supporting higher-load distribution and balanced protection across phases.
• 600V rating makes it suitable for a wide range of commercial and industrial applications, delivering reliable protection in higher-voltage circuits.

Ideal use cases

• New installations in GE panelboards or OEM-compatible load centers requiring robust 400A, three-phase protection.
• Upgrading or retrofitting commercial or light-industrial distribution panels where secure mounting and dependable trip performance are essential.
• Applications with vibration-prone equipment or environments where long-term connection integrity matters.

Why this matters for your system

The combination of bolt-on rigidity and a thermal-magnetic trip unit means you get a circuit breaker that maintains strong electrical contact under load and responds predictably to faults. This reduces nuisance trips, minimizes downtime, and helps protect downstream equipment and wiring from damage caused by overloads and short circuits. By choosing a GE SGLA36AI0400, you’re selecting a unit designed to work seamlessly with GE’s OEM-rated panelboards and load centers, ensuring harmonized performance and easier serviceability.
