GE TJD432300 - 300 A, 240 V, 3-Pole Circuit Breaker | AmpState

Meet the GE TJD432300 — a 300A, 240V, 3-pole molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and load centers. Built to fit seamlessly into GE and compatible OEM panel systems, it’s a trustworthy choice for safe, continuous operation.

Why this breaker stands out

• Compact molded-case design: Efficient use of panel space without compromising protection, making it easier to organize dense electrical installations.
• Thermal-magnetic trip unit: Delivers stable, repeatable protection by responding to both overloads and short circuits with reliable trip characteristics over a wide range of operating conditions.
• 3-pole, 300A, 240V configuration: Ideal for protecting 3-phase feeders and equipment in commercial and light industrial environments.
• OEM-compatible: Designed to pair with matching GE load centers and panelboards, ensuring straightforward replacements and consistent performance.
• Versatile applications: Suitable for residential, commercial, and light industrial installations where robust branch-circuit protection is essential.

Concrete benefits in real-world setups

In a multi-room commercial space, the GE TJD432300 can shield essential feeders feeding lighting, HVAC, and power distribution, minimizing downtime and equipment damage during faults. In light industrial panels, its 3-pole design provides balanced protection for 3-phase motors and controlled loads, reducing nuisance trips and keeping production lines running smoothly. For upgrades or replacements, its OEM compatibility means you can swap in a unit that preserves panel labeling, trip characteristics, and overall system behavior without invasive modifications.

What problems it solves

• Prevents damaging current surges from becoming costly faults on major feeders
• Maintains panel organization and compatibility in GE-backed installations
• Delivers predictable trip behavior, helping technicians diagnose faults faster
• Supports a range of environments from small offices to light manufacturing by handling diverse load profiles

Practical tips for usage

• Ensure the panel is designed for a 3-pole, 240V circuit and that the bus structure accommodates the 300A unit.
• Verify that the replacement breaker matches the OEM panelboard’s trip characteristics to maintain consistent protection curves.
• Label feeders clearly in the panel to reflect the protection coverage provided by the TJD432300 for easier maintenance and troubleshooting.
• When planning upgrades, consider how the 3-pole configuration will balance loads across phases to optimize protection and performance.
