Siemens 3VA5130-4ED11-0AA0 0A 1-Pole 3 V Circuit Breaker Potential Transformer

Siemens 3VA5130-4ED11-0AA0 combines robust protection with integrated sensing in a compact, single-pole package. Designed for low-voltage control and monitoring, this circuit breaker features a 3 V voltage rating for its sensing/auxiliary output while delivering switching functionality in a streamlined footprint. The current rating is listed as 0 A, reflecting its specialized use as a protection/sensing module within Siemens protection systems.

Key details

• Part number: 3VA5130-4ED11-0AA0
• Poles: 1
• Voltage rating: 3 V
• Current rating: 0 A
• Type: Circuit breaker with integrated potential transformer
• Manufacturer: Siemens

Why this module stands out

In many control panels, you need both reliable circuit interruption and a safe, isolated sensing signal for meters, alarms, or control logic. This Siemens unit delivers both in a single, space-saving device. The potential-transformer integration means you can tap a low-voltage signal for monitoring without adding separate sensing hardware, reducing wiring complexity and potential points of failure.

Ideal use cases

• Panel assemblies and control cabinets where a compact protection device also provides a sensing output for instrumentation or data logging
• Siemens-based control systems that require synchronized protection and monitoring with a single component
• Retrofits or new builds in industrial environments where minimizing component count improves reliability and ease of installation

Benefits and outcomes

• Reduced wiring effort: One device supplies both switching protection and a low-voltage sensing signal
• Compact integration: Small footprint fits tighter panel layouts and reduces enclosure size
• Reliable signaling: Isolated 3 V sensing output supports accurate monitoring and control
• Siemens ecosystem compatibility: Seamless integration with other Siemens protection and control devices

Practical tips for installation and use

Verify compatibility with your Siemens protection scheme and ensure proper mounting within the panel according to manufacturer guidelines. Use the 3 V sensing pathway to feed your instrumentation or control logic, keeping the primary circuit isolated from the measurement side for safety and accuracy. This module is particularly well-suited for applications where space, reliability, and Siemens system cohesion are priorities.
