General Electric SGLB36CA0400 400A 3-Pole 600 V Circuit Breaker

Designed for demanding three‑phase power, the General Electric SGLB36CA0400 400A 3‑Pole 600 V Circuit Breaker delivers robust, reliable protection for high‑demand electrical systems. As a GE part (Part Number: SGLB36CA0400), this breaker is built to interrupt fault currents safely in industrial and commercial panels where heavy loads meet strict safety requirements.

• Part number: SGLB36CA0400
• Current rating: 400 A
• Poles: 3
• Voltage rating: 600 V

What makes this 400 A, 3‑pole unit stand out is its ability to protect large three‑phase circuits without compromising on selectivity or reliability. It’s purpose‑built for applications where three‑phase power drives significant equipment loads, helping to prevent damage from overloads and short circuits while minimizing unnecessary interruptions in everyday operations.

Ideal use cases

• Main feeder protection for large 3‑phase distribution panels in industrial facilities
• Protection for high‑demand equipment such as motors, compressors, and HVAC systems
• Service panels in manufacturing plants, data centers, and commercial buildings with heavy electrical loads

Why choose this GE circuit breaker

The SGLB36CA0400 is purposefully designed for environments where reliability and high current handling are non‑negotiable. For systems operating up to 600 V, this breaker provides decisive fault interruption while supporting continuity of service for non‑faulted circuits. It’s particularly well suited for installations where a 400 amp, 3‑pole solution is required to protect feeders and large motors without sacrificing panel space or safety margins.

Practical installation and care

• Confirm panel compatibility with GE SGLB series breakers and ensure the enclosure is rated for 400 A, 3‑pole operation at up to 600 V
• Follow all local electrical codes and manufacturer guidelines during installation
• Schedule professional servicing to verify proper seating, torque on connection points, and correct fault interrupt behavior
• Keep the surrounding area clean and dry to prevent arcing or contact damage during maintenance

In short, the General Electric SGLB36CA0400 400A 3‑Pole 600 V Circuit Breaker is a purpose‑built solution for serious three‑phase loads. It combines rugged construction with precise protection to safeguard high‑demand equipment and keep critical systems running smoothly.
