ge CKH3400 400A 3-Pole 600 V Circuit Breaker

The GE CKH3400 is a rugged, reliable circuit breaker designed for serious 3‑phase power protection. With a 400 A current rating, a 3‑pole configuration, and a 600 V maximum rating, this device is built to safeguard large motors, feeders, and distribution circuits in demanding industrial and commercial environments.

Key specifications at a glance

• Part Number: CKH3400
• Current rating: 400 A
• Poles: 3
• Voltage rating: 600 V

What it protects and how

Designed for three‑phase systems, the CKH3400 interrupts all three lines together to prevent imbalanced phasing and reduce the risk of damage from overloads or short circuits. This coordinated protection helps keep critical equipment—such as large motors, fans, pumps, and feeders—safer and easier to troubleshoot, while supporting safer shutdown procedures during faults.

Ideal applications

• Industrial facilities with heavy 3‑phase machinery and high‑current loads
• Commercial spaces that rely on three‑phase distribution for HVAC, manufacturing, or processing lines
• Electrical panels and disconnects in GE‑configured distribution systems that require a strong, single‑unit 3‑pole protection device

Why choose the GE CKH3400

• Directly aligned with GE CKH series configurations, offering a coherent, maintainable protection solution for existing GE installations
• A single, integrated device that protects all three phases, simplifying panel layout and reducing component count
• Durable construction designed to withstand the rigors of industrial environments while delivering consistent performance

Practical guidance and care

Ensure proper installation by matching the CKH3400 to your system’s voltage and current requirements, and verify compatibility with your GE panels and wiring practices. Regularly inspect for secure connections, signs of wear, and any tripped states that require reset or replacement. For safety, follow local electrical codes and rely on a licensed professional for installation and servicing.
