With a compact footprint and a three-pole design, it provides synchronized disconnection across all phases, helping protect equipment and personnel in demanding industrial and commercial applications. The product is specified with a voltage rating of 3 V and a current rating listed as 0 A, making it essential to verify its suitability for your exact installation before deployment.

Key specifications

• Product: Siemens 3VA5220-6ED31-0AA0
• Current rating: 0 A (as listed in the product details)
• Poles: 3
• Voltage rating: 3 V

What makes this 3-pole design stand out

• Three-phase protection in one unit: Controls all three conductors together, simplifying panel layouts and maintenance in three-phase systems.
• Compact, integrated protection: A single device that delivers coordinated disconnection for multi-line circuits, reducing wiring complexity and potential points of failure.
• Siemens reliability: Built on Siemens engineering standards, offering consistent performance and long-term durability in challenging environments.

Ideal use cases

• Three-phase industrial control panels and motor-distribution boards where coordinated shutoff is required
• Commercial or light-industrial equipment racks that require a simplified protection solution for three conductors
• Service enclosures and automation cabinets that benefit from a single, tri-phase protective device

How this part fits into your setup

• Compatibility mindset: Ensure the device’s 3 V rating aligns with your system voltage requirements and that the current rating (0 A as listed) matches the load and protection strategy you intend to implement.
• Installation considerations: Plan for a three-pole configuration to guarantee simultaneous disconnection of all phases, which helps minimize arc and residual energy during maintenance.
• Lifecycle and replacements: When replacing or stocking parts, reference the exact part number 3VA5220-6ED31-0AA0 to avoid mismatches in trip characteristics and terminal configurations.

Practical tips for maximizing value

• Double-check system voltage compatibility before installation to ensure the 3 V rating is appropriate for your distribution panel.
• Document the current rating as listed (0 A) and confirm it aligns with your protective coordination plan for safe operation.
• Store a spare unit from the same Siemens family in your equipment room to reduce downtime during panel servicing or upgrades.
