SEL-501 dual overcurrent relay elements
• Overcurrent protection for two (2) three-phase feeders
• Instantaneous overcurrent relay (ANSI device 50H)
• Neutral instantaneous overcurrent relay (ANSI device 50NH)
• Definite-time phase overcurrent element (ANSI device 50PT)
• Definite-time negative sequence overcurrent element (ANSI device 50QT)
• Definite-time neutral overcurrent element (ANSI device 50NT)
• Inverse-time phase overcurrent element (ANSI device 51PT)
• Inverse-time negative sequence overcurrent element (ANSI device 51QT)
• Inverse-time neutral overcurrent element (ANSI device 51NT)
Eaton combines field-proven apparatus and controls by integrating Cooper Power™ series VFI underground distribution switchgear with Schweitzer Engineering Laboratories (SEL) distribution protection relays to provide a robust, innovative, fully integrated Smart VFI switchgear package.
• Feeder protection
• Consists of two independent three-phase overcurrent relays in a single package; each independent relay is configurable, enabled by user settings
• Automation and control
• One SEL-501 relay per three-phase feeder overcurrent protection, automation and control capabilities in an integrated package; includes battery backup power, as well as built-in metering functions
• Event analysis
• Detailed event records available
• Communications
• Integrate the SEL-501 relay into serial or Ethernet-based communications with IEC 61850, IEC 60870-5-103, Mirrored Bits communications, Modbus and DNP3 protocols
• Programming
• User-friendly programming template for quick and easy setup
• Included options
• Power supply/control input voltage: 24 Vdc / 24 Vdc
• Communications port: EIA-232
