Introducing the Siemens EH3A030 Circuit Breaker—a precise, three-pole overcurrent protection device designed for 480V three-phase power systems. Built for maintenance, retrofit, and replacement projects, this 30A breaker keeps your industrial distribution reliable while aligning with existing Siemens infrastructure.

  • Amperage: 30 A
  • Poles: 3-Pole
  • Voltage rating: 480 V

Key advantages

  • Direct compatibility with panels and equipment designed for EH3A030, making it a dependable replacement when the part number EH3A030 is required.
  • Three-pole coordination ensures simultaneous disconnection of all phases, improving safety and reducing the risk of phase imbalance during faults or startup.
  • Compact form factor and Siemens engineering guarantee consistent performance in demanding industrial environments.

Use cases and scenarios

  • Retrofit an existing 480V, three-phase distribution panel where the EH3A030 specification matches the original design.
  • Replace worn or failed breakers in manufacturing lines, data centers, or heavy equipment rooms that rely on 3-phase protection.
  • During routine maintenance, swap in an identical EH3A030 to minimize downtime and preserve system electrical characteristics.

Compatibility and installation notes

  • Always confirm fit and ratings before ordering. The part number EH3A030 is the best reference for compatibility with your system.
  • Verify that your panel or chassis supports 480V three-phase operation and 30A overcurrent protection.
  • For safe installation, de-energize the circuit and follow standard electrical safety practices. If you’re unsure, consult a licensed electrician or the equipment manufacturer’s guidance.

Why Siemens for overcurrent protection

  • Renowned reliability and consistency across industrial power systems.
  • Standardized specs that simplify stocking and maintenance across multi-site operations.
  • Direct replacement in environments where Siemens EH3A030 is specified, reducing configuration or mounting challenges.
