Arc-Flash Solutions
SEL combines light-sensing technology with fast overcurrent protection to provide high-speed arc-flash detection (AFD). Combining these technologies allows high-speed tripping during arc-flash events without overtripping for external faults.
Reduce Arc-Flash Hazards
To validate the arc-flash detection performance of the SEL-751 and SEL 849 Relays, a series of tests were performed at a high-current laboratory. This video shows the difference in arc-flash intensity with and without SEL arc-flash protection.
motorMAX Low-Voltage Motor Management and Protection System
motorMAX is the SEL smart motor control system for low-voltage motor control centers (MCCs). This scalable system includes protective relays, managed network switches, real-time automation controllers (RTACs), precise time sources, and machine interfaces for local and remote visualization and control.
