Siemens 3VA4150-5ED34-0AA0 - 50 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Siemens 3VA4150-5ED34-0AA0, a 50 A, 600 V, 3-pole molded case circuit breaker designed to guard your panelboards and load centers with dependable branch circuit protection. Built for reliability in real-world electrical environments, it delivers precise, repeatable protection for both overcurrent and short-circuit events.

Key Benefits

• Compact molded case design minimizes space usage in crowded panels, making it ideal for installations where panel real estate matters.
• Thermal-magnetic trip unit provides stable, repeatable protection by responding to both sustained overloads and instantaneous short circuits, helping to prevent nuisance tripping and gear damage.
• 3-pole configuration ensures coordinated protection across three phases with a common trip, enhancing safety and trip consistency in three-phase systems.
• OEM-compatible designed to pair seamlessly with matching Siemens load centers and panelboards, simplifying replacements and upgrades.
• Versatile applications suitable for residential, commercial, and light industrial environments where reliable protection is critical.

Ideal Use Cases

• Panelboard and loadcenter upgrades in existing electrical rooms where space is at a premium.
• New installations in light commercial spaces that require dependable three-phase protection.
• Retrofits in residential split-bace or multi-load panel configurations needing a robust, common-trip solution.

Why It Matters

Protection in electrical systems isn’t just about cutting power when things go wrong—it's about controlling fault currents safely and predictably. The 3VA4150-5ED34-0AA0’s thermal-magnetic trip mechanism delivers fast response to short circuits while avoiding unnecessary interruptions from minor overloads. The result is safer equipment, reduced downtime, and smoother maintenance cycles in the kinds of spaces where reliability is non-negotiable.
