GE SGLC3604L4XX - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

GE SGLC3604L4XX is a robust, bolt-on molded case circuit breaker designed to protect your electrical system where it matters most—panelboards and loadcenter assemblies. At 400 A and 600 V, this 3-pole unit from AmpState delivers dependable branch circuit overcurrent and short-circuit protection for demanding commercial and light industrial environments, as well as residential panels that demand serious protection.

• Bolt-On Mounting: Secure, vibration-resistant bus connections that stay seated under equipment vibration and building movement, reducing connection wear and excursions over time.
• Thermal-Magnetic Trip Unit: Dual-action protection that blends a thermal overcurrent response with a magnetic short-circuit trigger for fast, repeatable trips when faults occur—helping prevent damage and downtime.
• Three-Pole, 400 A, 600 V: Ideal for three-phase circuits and heavy feeders, offering substantial protection for larger loads while maintaining reliable performance across typical panelboard configurations.
• OEM Load Center Compatibility: Designed to integrate smoothly with matching GE OEM load centers and panelboards, ensuring consistent protections and streamlined field service.
• Versatile Applications: Well-suited for residential, commercial, and light industrial installations that require solid, long-lasting circuit protection for branch circuits and critical equipment.

With this GE bolt-on breaker, you get a compact yet capable protective device that’s built to endure the rigors of demanding electrical environments. The combination of sturdy mounting, precise thermal-magnetic protection, and seamless compatibility with GE load centers makes it a practical upgrade or replacement choice when you need reliable, field-serviceable protection for large-draw circuits. Specifically, it protects your system from the most common electrical faults: overloads that creep up over time and sudden short-circuit faults that can cause arc-flash risks and equipment damage. Its 3-pole design ensures synchronized protection across all phases, which is critical for balanced, safe operation in three-phase panels. Whether you’re upgrading an existing panel, stocking a maintenance shelf for critical infrastructure, or wiring a new commercial installation, this breaker provides a dependable, long-term solution. Ideal use scenarios include reinforcing main feeders in panelboards that serve machinery, HVAC equipment, manufacturing lines, or data-center ancillary circuits—where uninterrupted protection and solid mechanical connections matter most. Its bolt-on architecture also simplifies replacement in field service, reducing downtime and preserving panel integrity.
