Siemens 3VA5112-4EC31-0AA0 0A 3-Pole 3 V Circuit Breaker Potential Transformer

Introducing the Siemens 3VA5112-4EC31-0AA0 — a purpose-built, three-pole circuit breaker with an integrated potential transformer designed to streamline protection and voltage sensing in low-voltage electrical systems. This unit is specified with a current rating of 0 A, features 3 poles, and carries a 3 V voltage rating, with the exact part number 3VA5112-4EC31-0AA0 ensuring precise compatibility in Siemens-based installations.

• Three-pole configuration provides balanced protection across all three phases in a compact footprint, ideal for coordinated protection in three-phase distribution boards and switchgear.
• Integrated potential transformer delivers measurement signals to protection relays and metering equipment without the need for separate transformers, simplifying wiring and reducing panel complexity.
• 3 V sensing capability aligns with low-voltage monitoring and relay input requirements, enabling reliable voltage sensing directly from the device.
• 0 A current rating (as listed) suggests the device’s primary function centers on sensing and protection interfacing rather than carrying main load, making it well-suited for panel integration and signaling roles within Siemens systems.
• Siemens compatibility ensures seamless integration with Siemens protection relays and switchgear, promoting consistent performance and straightforward maintenance within existing Siemens architectures.
• Space-saving, integrated solution combines protection and sensing in a single component, helping to reduce cabinet depth and wiring complexity in control panels and motor control centers.

Ideal use scenarios include industrial control panels, three-phase distribution boards in factories and data centers, motor control centers, and test benches where reliable protection together with accurate voltage sensing is essential. By using the Siemens 3VA5112-4EC31-0AA0, you gain a streamlined installation with fewer parts to configure, faster commissioning, and a cohesive performance profile compatible with Siemens protection ecosystems.
