Managed Ethernet Switch
The SEL-2740M is designed for the harsh conditions found in energy and industrial environments. The switch supports communications infrastructure built for engineering access, supervisory control and data acquisition (SCADA), and real-time data communications, while offering the same reliability found in SEL protective relays. The SEL-2740M meets or exceeds the IEEE 1613 (Class 2), IEC 61850-3, and IEC 60255 industry standards for vibration, electrical surges, fast transients, extreme temperatures, and electrostatic discharge for communications devices in electrical substations.
