Siemens 3VA6115-6HL31-0AA0 0A 3-Pole 3 V Circuit Breaker Potential Transformer

Meet the Siemens 3VA6115-6HL31-0AA0, a purpose-built 3-pole circuit breaker with an integrated potential transformer. Designed for precise protection and reliable monitoring in three-phase systems, this compact unit blends Siemens engineering excellence with practical, real-world utility. If you’re upgrading control panels or modernizing switchgear, this module delivers a streamlined solution that reduces wiring complexity while maintaining robust performance.

• Part number: 3VA6115-6HL31-0AA0
• Current rating: 0 A
• Poles: 3
• Voltage rating: 3 V

Why this combination matters

By pairing a 3-pole circuit protection device with a 3 V potential transformer in a single housing, this unit simplifies installation in three-phase environments. The integrated transformer enables safe, accurate measurement and monitoring of system conditions without requiring separate sensing components, helping protect equipment and improve fault diagnosis.

Ideal use cases

• Three-phase control panels and distribution boards where space and integration are priorities
• Instrumentation and metering circuits that benefit from a built-in potential transformer for signal monitoring
• Retrofits in compact switchgear where a single, consolidated module saves panel space

What sets it apart

• Consolidated protection and measurement: reduces wiring, simplifies panel layouts, and lowers assembly time
• Siemens reliability: engineered for consistent performance in demanding electrical environments
• Three-pole configuration: ideal for balanced three-phase systems, providing synchronized protection and monitoring across all phases

Practical considerations

Before integrating, ensure compatibility with your panel’s architecture and signaling needs. The 3 V rating is suited for low-voltage sensing applications, and the 0 A current rating indicates a specific protection/profile for this variant. This module is designed to fit within standard Siemens-compatible switchgear, offering a straightforward path for upgrades or replacements.
