GE SGPA36AT0400 - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Introducing the GE SGPA36AT0400 — a robust 400A, 600V, 3-pole bolt-on molded case circuit breaker designed to guard panelboards and load centers against overcurrent and short circuits. Built for reliability in demanding electrical environments, it delivers consistent protection when it matters most.

Key design advantages that translate to real-world performance:

• Secure bolt-on mounting: provides a rigid, vibration-resistant bus connection, helping maintain electrical integrity in crowded panels or spaces with movement.
• Thermal-magnetic trip unit: combines precise thermal protection with fast magnetic trip for predictable responses to overloads and short circuits, reducing nuisance trips and safeguarding connected equipment.
• OEM-compatible: engineered to drop into GE-compatible load centers and panelboards without adapters or rewiring, streamlining installation and service work.
• Versatile application: ideal for residential, commercial, and light industrial electrical distributions that require dependable branch-circuit protection.

Technical snapshot

• Amperage Rating: 400 A
• Voltage Rating: 600 V
• Poles: 3
• Mounting: Bolt-on
• Trip Type: Thermal-magnetic molded case
• Application: Branch circuit overcurrent and short-circuit protection

Why this breaker stands out: the bolt-on design ensures a secure, durable connection in installations where vibration or tight panel spaces can challenge reliability. The thermal-magnetic trip mechanism delivers stable, repeatable protection that responds quickly to sudden faults, while preserving normal operation during minor overloads. Paired with GE’s compatible load centers, it simplifies replacement and routine maintenance, minimizing downtime in critical electrical systems.

Ideal use scenarios:

• Replacing aging or undersized breakers in GE load centers within homes or light commercial spaces
• Upgrading panel distribution in small offices, shops, or workshops that require robust 400A protection up to 600V
• Locations with vibration or crowded panel configurations where a secure, bolt-on connection enhances long-term reliability
