Advanced Safety Systems

Intelligent Auto-Trip Isolation

Proprietary voltage monitoring system instantly disconnects main circuits when control voltage drops below 198V AC, preventing unsafe operation during power anomalies.

High-Energy Fault Containment

8KA/1sec short-circuit rating with reinforced busbar structure contains arc flash incidents, reducing incident energy to <8 cal/cm² at 450mm distance.

Compact Safety Design

Optimized 700×700×1700mm dimensions with <300kg weight enable installation in confined electrical rooms while maintaining 50mm arc-resistant gaps.

Performance Validation

8kA Short-Circuit Test

Zero deformation after 3-phase fault simulation at 8kA/1sec with 0.8 power factor (IEC 62271-200 verified)

Isolation Response Time

Full circuit disconnection within 85ms of voltage loss (exceeds IEC 60947-2 requirements)

Thermal Management

Maximum 65°C temperature rise at 800A continuous load (IEC 61439-1 compliant)
