Siemens 3VA5150-5ED31-0AA0 50A 3P 600V Circuit Breaker | AmpState

Meet the Siemens 3VA5150-5ED31-0AA0, a purpose-built 3-pole, 50-amp circuit breaker designed to protect complex electrical distributions in panelboards, load centers, and distribution boards. With a 600V rating, this breaker is engineered to perform reliably in three-phase systems where robust fault protection matters most.

Key reasons this part stands out

• Exact part number compatibility: 3VA5150-5ED31-0AA0 ensures a precise fit in Siemens panelboards and compatible enclosures, simplifying retrofits and service planning.
• Three-pole configuration at 50 A: ideal for safeguarding feeders and multi-branch circuits in 3-phase installations without compromising space or wiring efficiency.
• 600V system compatibility: suitable for commercial and light-industrial environments that run higher-voltage distribution networks.
• Retrofit and maintenance readiness: designed for scenarios where preserving a consistent part number streamlines procurement, inventory control, and long-term maintenance scheduling.
• Trusted source for availability: AmpState offers this genuine Siemens breaker, helping minimize downtime with dependable stock and timely fulfillment.

Practical use cases you’ll appreciate

• Upgrading or maintaining Siemens-based panelboards and load centers in offices, hospitals, manufacturing facilities, or data centers, where reliable protection is essential.
• Strategic spare-part planning: keep a compatible 3-pole 50A breaker on hand to avoid last-minute substitutions that could affect protective coordination.
• Project planning and long-term maintenance: align with existing Siemens protective devices to preserve coordinated trip curves and predictable performance across the distribution network.

What this Siemens circuit breaker delivers

• Consistent, real-world protection: sensitive enough to interrupt fault currents above 50 A, helping prevent damage to downstream devices and wiring.
• Compact, compatible form factor: 3-pole design integrates cleanly into standard Siemens enclosures without unnecessary clutter.
• Genuine Siemens reliability: built on Siemens’ long-standing track record in critical electrical installations, providing durability and predictable behavior over time.
