Product overview
Aegis EcoTec is a 12 kV front-cable-entry ring main unit for secondary-distribution applications. Lucy Electric describes the insulation medium as synthetic air with zero global-warming potential, paired with vacuum interruption.
Verified configuration
The official page lists 50 Hz operation, a circuit-breaker current range including 250 A and 630 A, and 20 kA short-time withstand for 3 seconds. It references the IEC 62271 series for switching, disconnecting and metal-enclosed switchgear functions.
Engineering significance
The product offers an established RMU format without SF6 for projects requiring front cable access. It should be compared on complete arrangement, operator safety, cable interfaces and automation options—not insulation terminology alone.
Specification caution
The 630 A structured value is the upper published circuit-breaker current. Confirm the selected way, protection arrangement, internal-arc class, ambient limits and market-specific documentation before specification.
