Siemens 3VA5130-5ED11-0AA0 0A 1-Pole 3 V Circuit Breaker Potential Transformer

Introducing the Siemens 3VA5130-5ED11-0AA0 — a compact, single-pole circuit breaker equipped with an integrated potential transformer. With a 3 V rating and a 0 A current rating, this device is designed to protect electrical circuits while providing precise sensing capabilities for real-time monitoring and metering in space-constrained control panels.

Why this Siemens device stands out

• Integrated potential transformer delivers direct sensing and measurement data without the need for separate transformers, simplifying wiring and improving installation efficiency.
• 1-pole design offers straightforward integration into existing panels where a compact protection-and-sensing solution is required.
• 3 V voltage rating aligns with specialized low-voltage protection and monitoring applications, enabling accurate fault detection and energy measurement within compatible systems.
• Part number transparency (3VA5130-5ED11-0AA0) ensures traceability and easy cross-reference with Siemens documentation and compatible accessories in the 3VA family.
• Robust Siemens engineering combines protection performance with reliable sensing, supporting safer, more predictable panel operation in industrial and automation environments.

What problems it solves and practical benefits

For control cabinets and automation panels where space is at a premium, this device eliminates the need for a separate transformer and additional wiring to monitor current and voltage. The built-in potential transformer provides timely, accurate data for:

• Protective coordination and fault detection — quickly identifies abnormal conditions to prevent equipment damage.
• Energy monitoring and metering — enables precise tracking of consumption and load behavior for better energy management.
• Simplified installation — fewer components mean shorter commissioning times and tighter panel layouts.

Ideal use scenarios

• Protection and monitoring in compact control panels and automation enclosures.
• Low-voltage protection schemes that benefit from integrated sensing to streamline wiring and diagnostics.
• retrofit or new-build projects where minimizing component count improves reliability and space utilization.
