Siemens 3VA4150-4ED34-0AA0 50A 3P 600V Circuit Breaker | AmpState

Meet the Siemens 3VA4150-4ED34-0AA0, a purpose-built circuit breaker engineered to protect panelboards, load centers, and electrical distribution networks from overloads and faults. With a robust 50 A rating, a 3-pole configuration, and a 600 V capacity, this unit handles demanding three‑phase service with dependable protection.

This breaker is purposefully selected for retrofit work and maintenance planning where the part number must remain consistent. Keeping the exact part number simplifies ordering, stock management, and service routines, helping minimize downtime when replacements are needed.

Designed to integrate smoothly within Siemens-based installations, the 3VA4150-4ED34-0AA0 aligns with the broader 3VA family for reliable coordination with upstream and downstream protection devices. It’s a practical choice for electrical distribution designs that prioritize compatibility, predictable replacements, and long-term serviceability.

• Retrofit and modernization: swap in the exact part during panel upgrades or routine service without reconfiguring wiring or panel layouts.
• Maintenance planning: maintain a ready supply of the same 3VA breaker to minimize downtime during outages.
• 3-phase protection: ideal for commercial or industrial circuits requiring steady 50 A per leg in a 3P system.
• Siemens ecosystem compatibility: designed to harmonize with Siemens distribution gear, reducing coordination issues across protection tiers.
