The SEL-351R Recloser Control, derived from SEL's premiere distribution relay, the SEL-351 Relay, combines traditional recloser control functions with technologically advanced SEL relaying features such as phase and ground directional elements, multilevel under- and overfrequency trip and control, and high-accuracy metering. Compatibility with standard control cable and mounting dimensions makes retrofitting fast and convenient, and the large operator controls and simple settings make the SEL-351R very user friendly.

  • Plug-In Recloser Control Compatibility
    Plug-compatible replacement for Kyle®/Cooper Form 3, 3A, 4, 4A, 4C, 5, 6, FXA, and FXB recloser controls, including "EZ" recloser control settings for rapid installation. Programmable four-shot autoreclosing function with optional synchronism and voltage check logic to match a variety of reclosing practices. Sequence coordination logic to coordinate with downstream reclosers.

  • ACSELERATOR® QuickSet™ SEL-5030 Software
    Helps speed recloser control application settings by allowing you to develop settings off-line, program SELogic® control equations, and analyze post-fault event reports.

  • Relay and Recloser Compatible Time-Overcurrent Protection
    U.S. (IEEE) and IEC relay curves, user-programmable curves, and all traditional recloser curves included for maximum recloser control flexibility and coordination. Constant time adder, vertical multiplier, and minimum response time functions for additional flexibility. Optionally, use the SEL-5804 curve designer software to create custom curves for the SEL-351R.

  • Large Display and Operator Controls
    Large front-panel display and programmable operator control interface pushbuttons for easy recloser control. Control interface pushbuttons include "Lock" function to prevent inadvertent operation. Pushbuttons are preprogrammed and labeled with popular recloser control switch functions, but can be reprogrammed and relabeled to meet your unique application requirements.

  • Advanced 24 Vdc Battery Charging and Monitoring System
    120 Vac-powered battery charging system monitors and tests the 24 Vdc battery. Automatic sleep and local/remote wakeup function. 12 Vdc available for powering modems and radio communications equipment (6 W continuous, 13 W for 1 second).

  • Extra Cabinet Space
    Additional space inside recloser control enclosure is available to add communications equipment such as a cellular modem and point-to-point radio to integrate the recloser control into your distribution automation system.

  • Per-Phase Operations Counter
    Now you can monitor breaker or recloser contact wear for each individual phase for efficient maintenance planning and troubleshooting.

  • Improved Mirrored Bits® Communications for Use With Spread Spectrum Radios
    Increases the flexibility of relay-to-relay logic communications schemes for improved feeder performance.

  • Choose the right recloser control for your application. View the SEL recloser control comparison chart for comparison information on all SEL recloser controls.

  • Upgrade existing substation and pole-mounted Cooper recloser controls with plug-compatible SEL-351R Recloser Controls to improve protection, control, and monitoring functions.

  • Integrate and automate new and existing recloser installations to provide remote control, remote communication, and automated data collection.

  • Selectively control preferred and alternate source reclosers that serve critical customer loads using a Mirrored Bits communications link.

  • Selectively coordinate with upstream SEL-351 or SEL-351S Relays applied on a feeder breaker using a Mirrored Bits communications link for secure, high-speed fault clearing on distribution circuits.

  • Apply high-side transformer blown-fuse detection logic to protect customers from potentially damaging unbalanced voltages.

  • Add underfrequency load shedding to individual feeder and subfeeder recloser installations.

  • Use the built-in fault locator and fault type identification to efficiently dispatch line inspection and repair personnel, and identify recurring feeder trouble points to improve reliability.

  • Program recloser failure logic with SELogic control equations.

  • Use the oscillographic event report and Sequential Events Recorder (SER) data to measure and improve protection device coordination.

  • Use a cold load pickup scheme to prevent tripping on cold load inrush current.

  • Use ACSELERATOR Report Server SEL-5040 Software to automatically gather relay event reports on your PC and manage them with a database.

  • Use SEL-5010 Relay Assistant Software to manage your relay settings.

  • Use ACSELERATOR Analytic Assistant SEL-5601 Software to display oscillograms and vector diagrams to analyze event reports.

  • Stainless-steel enclosure

  • Three-phase and synchronism voltage input interface

  • EIA-485 communications port

  • DNP3 Level 2 Slave communications protocol with point mapping

  • Load profile

  • Mirrored Bits communications and load profiling

  • User-configurable labels for operator controls and target LEDs

  • Control and Low-Voltage Close Cables
    SEL manufactures and sells control and low-voltage close cables for connecting SEL-351R Recloser Controls to Cooper reclosers in new or retrofit installations. Both the control and low-voltage close cables are available in a 10-foot standard length. Custom-order cables are available on a per-foot basis up to 100 feet.

    • Control Cable - C510
    • Low-Voltage Close Cable - C515 (for use with the low-voltage close socket, 9250014, which provides an exterior receptacle on the SEL-351R enclosure that mates with C515)
    • Low-Voltage Close Cable - C516 (connects directly to the terminal block inside the SEL-351R enclosure)
    • Cables can be specified using the free SEL-5801 Cable Selector Program

     

  • Conformal Coating - Protect equipment from harsh environments and airborne contaminants such as hydrogen sulfide, chlorine, and moisture.
