Siemens 3VA6225-5HN31-0AA0 0A 3-Pole 3 V Circuit Breaker

Meet the Siemens 3VA6225-5HN31-0AA0, a compact 3-pole circuit breaker built for reliable protection in three-wire, low-voltage applications. With a single device handling three lines, it helps you streamline panel layout, reduce wiring complexity, and maintain clean, organized control cabinets in automation, manufacturing, and OEM environments.

Key specifications

• Current rating: 0 A
• Poles: 3
• Voltage rating: 3 V
• Part number: 3VA6225-5HN31-0AA0
• Type: Circuit Breaker
• Brand: Siemens

Why this 3-pole design matters

The 3-pole configuration means three separate current paths are protected within one unified device, making it an efficient choice for three-phase circuits or multi-line protection in compact control panels. This Siemens part is ideal when you need precise protection across multiple conductors without adding multiple individual breakers.

Ideal use cases

• Three-phase control panels in automated equipment and machinery
• OEM assemblies requiring a compact, integrated protection solution
• Low-voltage industrial installations where space and wiring efficiency are priorities
• Educational or training setups that demonstrate multi-line protection in a single unit

Key benefits and practical considerations

• Consolidated protection: A single 3-pole device covers three lines, simplifying wiring and reducing panel footprint.
• Source compatibility: Part number 3VA6225-5HN31-0AA0 aligns with Siemens systems and sourcing channels, helping with replacement parts and service continuity.
• Clear specifications for planning: The listed current rating (0 A) and voltage rating (3 V) should be validated against your system requirements to ensure proper operation and safety compliance.
• Durable construction for routine operation in industrial environments when installed per manufacturer guidelines.

Practical tips for deployment

Before integrating the Siemens 3VA6225-5HN31-0AA0, confirm panel compatibility with Siemens 3VA0/3VA series breakers and ensure your control cabinet wiring supports a 3-pole configuration. Follow standard torque specifications for terminal connections, and verify coordination with upstream protection devices to maintain proper selectivity and safety margins.

If your project calls for a precise, multi-line protection solution from Siemens, the 3VA6225-5HN31-0AA0 delivers a cohesive, three-pole approach in a single, compact package. Consider this part for reliable replacement or initial install where a three-line, low-voltage circuit breaker is required.
