GE TJJ426400 - 225 A, 600 V, 2-Pole Circuit Breaker | AmpState

The GE TJJ426400 is a 225 A, 600 V, 2-pole molded case circuit breaker engineered to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. With a compact design and robust thermal-magnetic protection, it provides reliable performance in demanding electrical environments—from home electrical panels to light commercial setups.

Key advantages that matter in real-world installs

• Space-efficient molded case design: slimmer profile than traditional breakers, freeing room for additional circuits and easier wire routing inside crowded panels.
• Thermal-magnetic trip unit: combines a stable thermal response for nuisance-free protection with an instantaneous magnetic trip for fast disconnection during short circuits.
• Two-pole construction: ideal for two-hot-line or 240V circuits, providing synchronized protection across both conductors.
• High-current, high-voltage capability: 225 A rating and 600 V rating make this breaker suitable for larger branch circuits and higher voltage systems common in commercial and light industrial applications.
• OEM panel compatibility: designed to work with matching GE OEM load centers and panelboards, ensuring consistent performance and straightforward replacement parts.
• Versatile applicability: suitable for residential, commercial, and light industrial deployments where reliable overcurrent and short-circuit protection is essential.

What problems does this breaker solve?

• Prevents damage from sustained overloads and sudden faults in branch circuits, protecting wiring, devices, and connected equipment.
• Provides predictable, repeatable protection across a range of panel configurations, reducing the risk of nuisance trips and unexpected outages.
• Offers a dependable upgrade path for panels requiring a robust 225 A, 600 V, 2-pole solution with seamless compatibility with GE load centers.

Ideal use scenarios

• Residential subpanels and large appliance circuits that demand strong protection without compromising space in the panelboard.
• Commercial distribution panels where 240V circuits and higher current loads are common.
• Light industrial electrical rooms that require reliable protection for feeders and equipment in moderate-duty environments.
