GE TJK436225WL - 225 A, 600 V, 3-Pole Circuit Breaker | AmpState

GE TJK436225WL is a 225 A, 600 V, 3-pole molded case circuit breaker designed to shield panelboards and loadcenters from overcurrent and short-circuit events. Built for dependable performance in residential, commercial, and light industrial environments, this breaker combines a compact footprint with precise protection to keep your electrical system safer and more reliable.

Key benefits that matter in real-world installations

• Compact molded-case design minimizes space consumption in crowded panels, making it easier to fit more circuits without sacrificing protection.
• Thermal-magnetic trip unit provides stable, repeatable protection by coordinating thermal and magnetic elements, delivering fast fault interruption when needed and preventing nuisance trips during normal load changes.
• OEM-load center compatibility is built for seamless integration with matching GE and other OEM panelboards and load centers, ensuring reliable fit, proper trip performance, and straightforward replacement.
• Versatile three-pole protection is ideal for three-phase systems, delivering balanced overcurrent and short-circuit protection for feeders and downstream equipment.
• Diverse application coverage suits residential panels, commercial distribution boards, and light industrial service entrances where robust 225 A, 600 V protection is required.

Practical use cases and installation scenarios

In a multi-branch residential panel, this 3-pole breaker protects three-phase feeds or can be used alongside single-pole devices to create a balanced distribution strategy. In commercial environments, it serves as a dependable main or sub-feed protection for panelboards supplying motors, HVAC gear, lighting, and receptacle circuits. In light industrial settings, it provides critical protection for distribution feeders and equipment rooms where 225 A at up to 600 V is required. The compact form factor helps maximize panel density, while the thermal-magnetic trip ensures predictable disconnection behavior under fault conditions.

Why this GE breaker is a smart choice

• Delivers clear, actionable protection data through its trip characteristics, helping electricians design safer, more reliable protection schemes.
• Reduces maintenance and replacement hassles due to robust, proven GE engineering and compatible form factor with OEM panels.
• Supports a wide range of installations—from new builds to panel upgrades—without sacrificing performance or compatibility.
