Brand: ABB
Series: ELK‑SP
Core Function: Arc flash detection and protection unit for medium‑voltage switchgear, fast arc‑fault tripping
Product Type: Arc Protection Relay / Arc Flash Detection Module
Key Specifications: High‑speed arc light sensing, configurable trip logic, self‑supervision, multi‑sensor input, alarm contacts
The ABB ELK‑SP3 2GHV055301A0101 is a dedicated arc‑flash protection unit designed for medium‑voltage metal‑clad switchgear compartments. It detects dangerous arc‑flash events via optical arc sensors and delivers ultra‑fast trip commands to circuit breakers to minimize equipment damage and personnel hazard caused by internal arc faults. The unit integrates light‑based fault detection, supervision logic and relay output circuits within compact hardware. Though original manufacturing has been terminated, it remains a critical spare component for maintenance and retrofit of legacy MV switchgear worldwide.
Series
ELK‑SP series is ABB’s legacy arc‑flash protection family for switchgear applications. The series includes multiple variants for different compartment layouts and sensor quantities. It works cooperatively with external optical arc sensors installed inside switchgear cabinets, focusing on rapid arc‑fault identification and breaker tripping, widely deployed across utility and industrial power distribution sites.
Product Features
- Ultra‑fast arc‑flash detection and trip response to mitigate arc‑blast damage
- Supports multiple optical arc sensor inputs for multi‑compartment coverage
- Built‑in continuous self‑diagnosis for sensor wiring and internal hardware health
- Configurable trip and alarm relay outputs for breaker tripping and remote alarm signaling
- Status LED indicators for local visual status and fault indication
