GE SGLL3604L3XX - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for demanding electrical systems, the GE SGLL3604L3XX delivers robust 400A, 600V protection in a compact 3-pole molded case circuit breaker. Designed for dependable branch circuit protection in panelboards and load centers, this unit combines rugged mounting with precise, repeatable trip performance to keep your downstream equipment safe and your system up and running.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the risk of loose connections in panels subject to vibration or movement.
• Thermal-magnetic trip unit offers stable, repeatable protection: the thermal element responds to sustained overloads while the magnetic element delivers an instantaneous trip for short-circuit events.
• 3-pole configuration delivers balanced, three-phase protection—ideal for modern commercial and light industrial electrical mains and feeders.
• OEM-compatible design is engineered to pair with matching GE OEM load centers and panelboards, simplifying installation and ensuring coordinated protection.
• Versatile applications suitable for residential, commercial, and light industrial environments where reliable branch-circuit overcurrent and short-circuit protection is essential.
• Part number SGLL3604L3XX confirms the exact specification for seamless sourcing and replacement in existing GE systems.

Why this GE breaker stands out

The combination of a bolt-on mount and a thermal-magnetic trip unit means you gain both mechanical reliability and precise electrical protection in one unit. With a 400A rating and 600V capacity, the SGLL3604L3XX is well-suited for main feeder applications, subfeed circuits, or critical distribution paths within panelboards and load centers. Its compatibility with GE OEM platforms helps maintain system integrity and simplifies maintenance when upgrading or expanding existing installations.
