Key specifications and compatibility

• Amperage: 400 A
• Poles: 2-Pole
• Voltage rating: 600 V

Why this GE breaker stands out

This isn’t a generic protection device. It’s a precise match for GE panels and systems that require a 400 A, 2-pole, 600 V solution. The TJK426400 part number serves as the best reference for compatibility, making it the reliable choice for restoration projects where exact specs matter. By choosing the correct GE part, you reduce the risk of nuisance trips, improper fit, and compatibility issues that can extend downtime.

• Exact compatibility: Specifically identified GE part designed for integration with GE equipment and retrofit scenarios.
• High-current protection: 400 A capacity protects heavy-load circuits commonly found in industrial and commercial applications.
• Two-pole safety: Simultaneous disconnection of both conductors enhances protection for multi-wire circuits.
• 600 V rating: Suitable for medium- to high-voltage environments typical in service entrances, panels, and controlled-distribution setups.
• Efficient replacement: Ideal for maintenance, retrofit, and replacement needs to keep systems up and running with minimal disruption.

Ideal use cases

• Replacing an aging or failed breaker in commercial or industrial electrical panels
• Retrofits or panel upgrades that require higher-current protection without changing entire assemblies
• Maintenance windows where a like-for-like 400 A, 2-pole, 600 V unit maintains system integrity

How to verify compatibility

Before ordering, confirm fit and ratings by cross-checking the exact part number. The TJK426400 is the best reference for compatibility with your GE equipment—match the amperage (400 A), number of poles (2), and voltage rating (600 V) to your panel requirements.

Installation and safety tips

• Power down and de-energize the circuit before removal or installation.
• Follow all applicable electrical codes and the equipment manufacturer’s guidelines.
• Have a qualified electrician perform the replacement to ensure proper torque and secure connections.

protect your electrical infrastructure with a breaker that's engineered to align precisely with GE designs. The General Electric TJK426400 offers the reliability, compatibility, and performance you need for effective, long-lasting circuit protection.
