GE SGLL3604L4XX - 400 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered by General Electric, the GE SGLL3604L4XX is a 400A, 600V, 3-pole bolt-on molded case circuit breaker crafted to protect large branch circuits in panelboards and load centers. When you need dependable protection for demanding electrical spaces, this breaker delivers with precision and durability.

Rock-solid mounting for dependable performance

Secure bolt-on mounting creates a rigid, vibration-resistant bus connection. In environments with vibration, frequent panel access, or mechanical stress, this design helps maintain a stable current path and reduces the risk of loose connections that can lead to overheating or nuisance trips.

Thermal-magnetic protection you can trust

The SGLL3604L4XX features a thermal-magnetic trip unit for stable, repeatable protection. The thermal element responds to overload currents with a controlled, time-delayed trip, while the magnetic element actuates instantly on severe short-circuit conditions, delivering rapid interruption to safeguard conductors and equipment.

Designed for compatibility and easy upgrades

Compatible with GE OEM load centers and panelboards, this 3-pole breaker simplifies replacements and panel modernization. Using a matching spec breaker ensures correct trip characteristics and a precise mechanical fit, speeding service calls and reducing field issues.

Ideal applications and practical use cases

Perfect for residential, commercial, and light industrial environments that require robust 3-phase protection. Use the GE SGLL3604L4XX as a main feeder in panelboards, as a critical upgrade during panel modernization, or as part of a broader branch-circuit protection strategy in service panels and distribution panels. The 3-pole configuration protects all phases in a 3-phase system, with reliable performance across demanding loads.
