ARC FLASH PROTECTION
Protection
Description
ARC QUENCHING DEVICE
- Unique reusable design creates a three-phase low-impedance parallel path for fault current to flow thus extinguishing the arc fault in less than 4 ms. Configurable to existing\ new\ retrofit LV and MV switchgear\ Control gear\ GIS.
- Complies IEEE 1584 and tested as per IEC60947 and UL 2748.
- Provides category 0 or 1 protection as per NFPA 70
- Available upto 17.5 kV
- Permits live testing.
- Quick operation minimizes damaging thermal and pressure effects due to arc flash.
ARC FLASH RELAYS
- Dedicated Relays for processing fault signal in less than 7 ms
- Complies IEEE 1584 and type tested to IEC60255.
- Standalone
- Configurable to existing\ new\ retrofit LV and MV switchgear\ Control gear\ GIS.
- Unique design permits live testing.
- Pre-programmed with minimal setting
- Unique configuration enables selective control
- Feature to easily identify fault if any
ARC SENSOR
- Designed to pickup light signal in less than 1 ms
