Siemens 3VA5180-4EC31-0AA0 0A 3-Pole 3 V Circuit Breaker Potential Transformer

The Siemens 3VA5180-4EC31-0AA0 is a 3-pole circuit breaker with an integrated potential transformer, purpose-built for precise monitoring and dependable protection in three-phase electrical systems. With a current rating of 0 A and a voltage rating of 3 V, this unit is designed to integrate seamlessly into Siemens protection and metering architectures, simplifying wiring and control strategies without compromising reliability.

• Integrated potential transformer: Delivers measurement signals directly from the breaker, reducing extra components and wiring complexity while improving signal integrity for relays and metering equipment.
• Three-pole configuration: Ensures synchronized protection across all three phases, enhancing coordination in industrial power distribution and minimizing risk of phase imbalances.
• Genuine Siemens part (PN 3VA5180-4EC31-0AA0): Built-for-fit compatibility with Siemens protection relays, SCADA interfaces, and monitoring systems, simplifying spare parts inventory and service.
• Optimized for Siemens ecosystem: Designed to work within Siemens electrical distribution and automation schemes, reducing integration challenges and promoting reliable operation in demanding environments.

Ideal use scenarios include panel-building, OEM equipment, and retrofit projects where a compact, measurement-ready breaker is essential. It’s well-suited for three-phase distribution panels, test benches, and facilities that require integrated sensing to feed protection relays or metering instrumentation without assembling separate transformers.

• Use cases: New installations in Siemens-based control panels, retrofits for measurement-enabled protection schemes, and environments where minimizing wiring and component count is beneficial.
• Who benefits most: Electrical engineers, panel builders, and maintenance teams seeking a single-unit solution that combines protection with direct measurement capabilities.
• Practical tips: Verify compatibility with your Siemens protection and metering hardware, plan a clear wiring path for the potential transformer outputs, and keep the exact part number on hand for service and replacements.
