SEL-651R Advanced Recloser Control
The SEL-651R is an enhanced, high-quality control that provides advanced features to new and retrofit recloser applications. Six voltage inputs provide source- and load-side voltage sensing, ensuring safe and secure alternate source logic. Reduce system and customer impacts due to faults by using the single-phase trip capability. Improve feeder loading by using high-accuracy metering functions and harmonic control.
Easily power accessories with 40 W, 12 Vdc auxiliary power supply for applications requiring additional power, such as radios. Enable fast communications-assisted trip logic and communications functions through the SEL-patented Mirrored Bits® communications technology that provides bidirectional relay-to-relay digital communications. The SEL-651R is certified to IEEE C37.60 standards and is a plug-compatible replacement for 14-pin reclosers.
- Plug-In Recloser Control Compatibility
Plug-compatible replacement for most Kyle®/Cooper FXA, FXB, Form 3, 3A, 4, 4A, 4C, 5 and 6 recloser controls. Programmable four-shot auto-reclosing function with synchronism and voltage check logic to match a variety of reclosing practices and sequence coordination logic to coordinate with downstream reclosers. - Six Voltage Inputs
The SEL-651R has six voltage inputs for status of both sides of the switch. This allows for better switching decisions and more complex Automatic Network Reconfiguration. Low-Energy Analog (LEA) Option
Reduce costs and save space with six, 8-volt-maximum LEA inputs, which decrease the number of PTs needed on the load or source side of the recloser.
- acSELerator QuickSet® SEL-5030 Software
Develop settings offline and download to the recloser. The software automatically checks interrelated settings and highlights out-of-range settings. Template Storage
Quickly commission recloser controls with just the settings you need. Design custom templates for your specific applications with acSELerator QuickSet Designer® SEL-5031 Software to reduce field commissioning and standardize selected settings. Templates are stored on the recloser control for easy access when making settings changes.
- Relay and Recloser Compatible Time-Overcurrent Protection
U.S. (IEEE) and IEC relay curves and all traditional recloser curves for maximum recloser control flexibility and coordination. Constant time adder, vertical multiplier, and minimum response time functions for additional flexibility. - Single-Phase Trip and Reclose
The SEL-651R can control, trip, and reclose on single phases or trip three-phase based on a single-phase fault. Single-phase tripping keeps customers online that are not on the affected phase. - Advanced 12 Vdc Battery Charging and Monitoring System
120 Vac or 240 Vac powered battery charging system monitors and tests the 12 Vdc battery. Automatic sleep and local wakeup function. 12 Vdc available for powering accessories, modems and radio communications equipment (40 W continuous). - Mirrored Bits® Communications Technology
Provides fast and reliable relay-to-relay communication for advanced communications-assisted protection, network reconfiguration, and restoration schemes. Learn More > - 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. - 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 recloser control into your distribution automation system. Cabinet also features front and rear doors for easy access. - Per-Phase Operations Counter
Now you can monitor breaker or recloser contact wear for each individual phase for efficient maintenance planning and troubleshooting. - Harmonic Control and Metering
Monitor and control power quality with harmonic metering up to the 15th harmonic and control on Total Harmonic Distortion (THD). - Configurable Power Elements
Used for directional power and VAR flow. - Phase and Ground Directional Elements
Securely trip forward or reverse faults for overcurrent protection. SEL's Best Choice Ground Directional Element™ logic selects the best ground directional element for system conditions and eliminates settings. - Full-Function Clock Elements
Vary logic according to time of year/week/day to accommodate variations in load type depending on season or load needs. - Load Encroachment Logic
Prevents operation of phase overcurrent elements under high load conditions. - Fault Locating
Provides an accurate estimate of fault location even during periods of substantial load flow. - Voltage Sag/Swell/Interrupt (VSSI) Report
The VSSI report captures power quality data related to voltage disturbances over a long period of time. - Convenience 120 Vac GFCI outlet
Standard convenience outlet provided for laptop or other 120 Vac device. - High Reliability and Rugged Design
The SEL-651R withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards.
- Choose the right recloser control for your application. View the SEL recloser control comparison table for comparison information on all SEL recloser controls.
- Upgrade existing substation and pole-mounted recloser controls with plug-compatible SEL-651R Recloser Controls to improve protection, control, and monitoring functions.
- Increase the flexibility of relay-to-relay logic communications with improved Mirrored Bits communications for spread-spectrum radios; improve feeder performance.
- Integrate and automate new and existing recloser installations to provide remote control, remote communication, and automated data collection.
- Combine SEL fault indicators with recloser controls to pinpoint the exact location of a fault, even on lateral feeds, something neither product can do on its own. When a fault occurs, the SEL recloser control reports the distance from the recloser to the fault, however, for lines with branches, the recloser control cannot determine on which branch of the line the fault has occurred. By following the line along the tripped fault indicators the line crew can easily find the area of the fault.
- Selectively coordinate with upstream SEL-651R, SEL-351R, 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.
- Apply 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.
- Replace substation RTUs with the SEL-651R powerful SELogic and ample I/O capabilities, and also use it as a full-featured recloser control.
- Access the oscillographic event report and Sequential Events Recorder (SER) data to measure and improve protection device coordination.
- Enable 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.
