With a 630 A rating, a robust 3-Pole design, and a nominal 415 V operating voltage, this unit delivers dependable overcurrent protection for large three-phase circuits. Specifically chosen for maintenance, retrofit, and replacement projects, the VL630N ensures your system continues to run safely and efficiently while preserving existing panel and protection scheme specifications.

Key specifications

• Amperage: 630 A
• Poles: 3-Pole
• Voltage: 415 V
• Part number: VL630N

What sets the VL630N apart

• Built for reliability in industrial distributions, motor feeders, and large switchgear, delivering consistent protection for high-current applications.
• Designed for maintenance, retrofit, and replacement where exact spec matching is essential, helping you minimize downtime and compatibility concerns.
• Part of Siemens’ trusted family, with the VL630N serving as the definitive reference when confirming compatibility across compatible panels and protection schemes.

Ideal applications

• Maintenance and retrofit projects in commercial and industrial electrical systems that operate at 415 V three-phase.
• Replacement of aging protection in Siemens-compatible switchgear, motor control centers, and distribution boards.
• New installations where a large-capacity, three-pole circuit breaker is required to safeguard multi-motor or multi-line loads.

Buying guide and compatibility tips

To ensure a correct fit, use the VL630N as your primary compatibility reference. Always confirm fit and ratings before ordering. When planning your upgrade or replacement, verify that your panel or enclosure supports a 3-Pole, 415 V configuration and that the VL630N’s 630 A rating aligns with your load requirements. The part number VL630N is the most reliable indicator of compatibility, helping you avoid mismatches and unnecessary delays.

Practical considerations for installation and use

• Match the breaker to your three-phase system voltage (415 V) and current needs (630 A) to ensure proper protection and tripping behavior.
• Coordinate with existing protective devices and tagging schemes in your panel to maintain a coherent protection strategy.
• Inspect mounting interfaces and enclosure compatibility to facilitate a smooth retrofit or replacement in Siemens-compatible gear.
