General Electric delivers dependable protection for demanding three-phase power systems with the SGPC3604L3XX circuit breaker. This 400A, three-pole device is designed for maintenance, retrofit, and replacement scenarios where exact GE specifications are required, ensuring seamless integration with GE panels and downstream equipment.

Key specifications at a glance

• Amperage: 400 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Part number: SGPC3604L3XX

Why the 3-pole, 400 A, 600 V combination matters: a three-pole design provides balanced protection across all three phases in industrial and commercial installations, helping to prevent phase imbalances and reduce fault risks on the most demanding circuits. The 400 A rating supports high-current loads typical of distribution panels, motor control centers, and service entrances.

Ideal use cases

• Maintenance and service upgrades where a precise GE specification is required
• Retrofits that must match existing GE equipment to preserve performance and compliance
• Replacement of aging breakers in panels, MCCs, and switchboards that list SGPC3604L3XX as the compatible model

How to verify compatibility

Before ordering, confirm fit and ratings by cross-checking the panel label and catalog requirements. The SGPC3604L3XX part number is the most reliable reference for compatibility, ensuring the panel’s listed specs align with 400 A, 3-Pole, 600 V operation. If uncertainties arise, consult the panel documentation or a qualified electrician to validate the match.

Practical guidelines for installation and care

Safety first: disconnect power and follow proper lockout/tagout procedures. Use appropriate PPE and adhere to manufacturer mounting torque and trip testing guidelines. Consider stocking a spare SGPC3604L3XX for planned maintenance or unexpected outages to minimize downtime and keep critical loads online.

Why choose a genuine GE part

Choosing a genuine GE SGPC3604L3XX provides assured compatibility with GE panels, consistent trip characteristics, and reliable long-term performance. This minimizes the risk of mismatches that can occur with generic replacements and supports smoother commissioning, testing, and ongoing maintenance.
