Product Description
The Schneider VAMP 321 is a high-performance central unit designed for comprehensive arc flash protection and power system monitoring. The BBAAD-DAADA-A1 configuration represents a versatile modular assembly that combines ultra-fast arc detection with standard overcurrent and earth-fault protection. By utilizing both light (optical) and current sensing, the unit effectively eliminates nuisance trips while providing a sub-millisecond reaction time to internal arc faults, significantly reducing the risk of equipment damage and personnel injury.
Application Areas
- Medium Voltage Switchgear: Primary protection for busbars, cable compartments, and breaker cells.
- Low Voltage Motor Control Centers (MCC): Protection of high-power distribution boards in industrial sites.
- Wind Power Generation: Specialized protection for turbine nacelles and collection substations.
- Data Centers: Ensuring power continuity by isolating arc faults in critical infrastructure racks.
Product Specifications
- Weight: 2.20 kg
- Dimensions: 153 mm x 218 mm x 205 mm (H x W x D)
- Country of Origin: Finland
- Protection Rating: IP54 (Front panel)
Operating Precautions
- Sensor Placement: Ensure optical arc sensors are positioned with a clear line of sight to potential fault points (e.g., busbar joints) and are free from dust or paint.
- Redundancy Wiring: When using external I/O units, ensure the communication loop is supervised to maintain high system availability.
- Current Thresholds: Set the overcurrent “and” gate high enough to avoid tripping during normal motor starting currents but low enough to detect arc-related current spikes.
- Light Interference: Avoid pointing sensors directly toward high-intensity artificial light sources or areas where external sunlight can trigger a false light signal.
