Product description
Shipping
Meet the Siemens 3VA5140-4EC31-0AA0, a purpose-built three-pole circuit breaker with an integrated potential transformer designed for robust protection and accurate metering in industrial power systems. Built by Siemens, this unit is part of the trusted 3VA family, engineered to deliver dependable performance in control panels, switchgear, and distribution boards.
Key specifications at a glance
- Current rating: 0 A
- Poles: 3
- Voltage rating: 3 V
- Part number: 3VA5140-4EC31-0AA0
What makes this device unique
Unlike standard breakers, this unit combines protective switching with an embedded potential transformer function in a three-pole footprint. The 0 A current rating indicates its role as a protection/measurement element rather than a conventional load-carrying device, while the 3 V rating specifies the system context in which it operates. The three-phase configuration ensures balanced protection across all lines, and the integration with a potential transformer supports metering, relay interfacing, and monitoring directly from the device.
Ideal use cases
- Three-phase protection and metering in industrial control panels and switchgear.
- Compact protection solutions for panel modernization where space is at a premium.
- Integrated measurement capability for accurate data to feed protection relays and energy meters.
Practical considerations and benefits
By combining protection and measurement in a single Siemens component, installers reduce wiring complexity and panel footprint. It simplifies stocking and maintenance by staying within the Siemens protection ecosystem, which helps ensure compatibility with Siemens relays, meters, and replacement parts. When planning a project, verify that the 3 V system context and the 0 A current rating align with your protection strategy and metering requirements.
