Benefits of compact and coordinated protection:

• Save up to 50% panel space: The EGARA and SSD combination halves panel footprint compared to generic upstream protection
• High system robustness: The EGARA and SSD safely withstand short-circuit currents up to 100 kA (Isccr)
• Minimise coordination errors: The SSD streamlines back-up protection selection for safer, easier dimensioning
• Complete diagnosis: Remote end-of-life indication for the EGARA and SSD simplifies maintenance and safeguards service continuity
• Fully compliant: The EGA 1 and SSD meet IEC 61643-11 and align with upcoming prIEC TS 61643-06 standards
