Key specifications at a glance

• Manufacturer: Siemens
• Part Number: 3VA62255JQ310AA0
• Amperage: 250 A
• Poles: 3 (three-phase)
• Voltage: 480 V
• Application: Circuit protection for panelboards, load centers, and electrical distribution

Why this model stands out

• Consistent part-number compatibility: Ideal for retrofit projects and ongoing maintenance where exact identification must remain unchanged, reducing downtime and minimizing compatibility questions.
• Robust three-phase protection: Designed to handle 250 A across three poles, enabling reliable protection in commercial and industrial electrical systems.
• Siemens reliability in distribution: Engineered for installation in common Siemens panelboards and distribution layouts, helping maintain uniform performance across assets.

Practical use cases

• Upgrading or replacing a worn breaker in existing Siemens installations without altering the original part number.
• Retrofitting older electrical systems that require a 250 A, 3-phase, 480 V protection scheme to support higher load centers or expansion plans.
• Stocking for maintenance programs where technician teams prefer consistent, field-verified part numbers for faster service calls.

How it fits into your project

• Placement considerations: Use in panelboards and load centers that specify 480 V three-phase protection. Confirm the breaker’s fit with your specific Siemens distribution equipment and housing dimensions as part of standard compatibility checks.
• Installation mindset: Plan for routine maintenance windows where a drop-in replacement minimizes system downtime and keeps electrical distribution operating smoothly.
