Siemens 3VA5125-4ED11-0AA0 25A 1P 415V Circuit Breaker | AmpState

Meet the Siemens 3VA5125-4ED11-0AA0, a purpose-built circuit breaker designed for reliable circuit protection in panelboards, load centers, and electrical distribution systems. With a 1-pole configuration, a 25 A rating, and a 415 V operating capability, it’s built to support everyday electrical work, retrofit projects, and careful maintenance planning where keeping the exact part number matters.

This model shines when a like-for-like replacement is required. The 3VA5125-4ED11-0AA0 preserves the precise fit and electrical characteristics you rely on, making retrofit work smoother and maintenance orders more predictable. Ideal for single-phase distribution, it ensures your Siemens installations stay consistent and properly documented, even as components require refreshment over time.

• 25 A protection for typical branch circuits in commercial and light-industrial settings
• 1‑pole design for straightforward single-phase protection
• 415 V rated to handle standard industrial electrical environments
• Exact part match to simplify retrofits and avoid compatibility issues
• Panelboard and load center compatibility—seamless integration with existing Siemens protection devices
• Reliable sourcing from AmpState for quick procurement and consistent supply

Who should consider this breaker? electricians performing upgrades or replacements in established Siemens installations, facilities teams conducting preventive maintenance, and project planners who prioritize consistent part numbers to minimize downtime and documentation complexity.

Why this matters in practice: selecting a breaker with the same form factor and electrical characteristics reduces the risk of misfits, shortens installation time, and delivers predictable performance during overload or fault conditions. The Siemens 3VA5125-4ED11-0AA0 is designed to deliver steady protection you can trust when it matters most—during commissioning, routine operation, and ongoing service.

Before installation, verify the panel labeling and confirm compatibility with your existing equipment. If you need a hand confirming fit, AmpState is ready to help you validate the match and ensure you’re ordering the exact replacement you need.
