GE SGLL36AT0400 - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The GE SGLL36AT0400 is a robust 400A, 600V, 3-pole bolt-on molded case circuit breaker designed to shield large branch circuits in panelboards and load centers. Built for dependable protection in residential, commercial, and light industrial environments, it pairs solid construction with precise trip performance to keep electrical systems safe and downtime minimal.

• Secure bolt-on mounting: Provides a rigid, vibration-resistant connection to the bus, helping maintain a stable electrical path even in busy electrical rooms or where equipment experiences movement.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection—thermal sensing handles sustained overloads while magnetic sensing responds instantly to high fault currents, minimizing damage and downtime.
• High-current capability: 400A rating supports large feeders and service distribution, reducing the need for multiple lower-capacity devices and simplifying panel design.
• 600V insulation and rating: Suitable for commercial and light-industrial distribution where higher voltage tolerance improves safety margins and compatibility with diverse equipment.
• 3-pole design: Provides complete three-phase protection essential for balanced distribution in modern panelboards and OEM load centers.
• OEM load center compatibility: Engineered to integrate seamlessly with matching GE and compatible OEM panels, streamlining replacements and upgrades without mismatches.
• Versatile application: Ideal for residential, commercial, and light industrial circuits requiring reliable branch circuit overcurrent and short-circuit protection.

Applications, compatibility, and practical installation insights

Use the SGLL36AT0400 to upgrade or replace high-amperage protection in existing GE panelboards or compatible OEM load centers. It’s well-suited for main feeder segments in commercial spaces, distribution to heavy-duty equipment, and systems where a single, high-capacity protective device simplifies wiring and maintenance. When selecting a bolt-on breaker, ensure the enclosure is designed to accept a 3-pole molded case unit and that the trip characteristics align with your protection plan for the connected loads.

Practical considerations include planning for spare capacity in the panel to accommodate future expansion and verifying that the panel’s bus configuration matches the bolt-on mounting requirements of the SGLL36AT0400. With its thermal-magnetic protection and solid GE build, this breaker helps maintain system reliability in busy electrical rooms and equipment-heavy environments.
