GE TJJ436400WL - 400 A, 600 V, 3-Pole Circuit Breaker | AmpState

GE TJJ436400WL: 400A, 600V, 3-Pole Molded Case Circuit Breaker

Engineered for demanding panel environments, the GE TJJ436400WL delivers reliable branch circuit overcurrent and short-circuit protection in a compact molded case. With a 400-amp rating and a 600-volt maximum, it's designed to handle high-demand loads in panelboards and loadcenters while keeping installation neat and space-efficient.

Designed for multi‑pole protection, this 3‑pole device ensures lands are tripped together in the event of a fault, helping to prevent dangerous half-switched circuits and ensuring safe disconnection across all phases.

• Thermal‑magnetic trip unit provides stable, repeatable protection across varying temperatures and load conditions, reducing nuisance trips and prolonging equipment life.
• Compact molded case design optimizes panel space, making it easier to fit large breakers in dense distribution boards.
• OEM panelboard compatibility works seamlessly with matching GE OEM loadcenters and panelboards, simplifying replacement or expansion projects.
• Versatile for multiple environments ideal for residential, commercial, and light industrial applications where robust protection and reliability matter.

This part, GE TJJ436400WL, is purpose-built for branch circuit overcurrent protection and short‑circuit interruption. Whether you're upgrading an aging panel, retrofitting a new commercial space, or reinforcing a light-industrial distribution system, this 3-pole circuit breaker offers the performance and compatibility you need.

Why choose this breaker? You get a proven thermal-magnetic protection solution from GE, designed to maintain consistent trip behavior under fluctuating loads. The 3‑pole configuration ensures synchronized disconnection during faults, which can improve safety and reduce downstream damage. Its compatibility with OEM panels minimizes retrofit headaches and ensures you can source parts quickly when you scale or service facilities.

Use cases and scenarios: replacing a failed 400A device in a GE or compatible panelboard, upgrading a service panel in a warehouse or workshop, feeding large motor loads in a small industrial setup, or expanding power distribution in a commercial suite where reliable protection is non-negotiable.
