Plug-In Recloser Control Compatibility
The SEL-351R is a plug-compatible replacement for Cooper Form 3, 3A, 4, 4A, 4C, 4D, 5, 6, FXA, and FXB recloser controls, including "EZ" recloser control settings for quick installation. The programmable four-shot autoreclosing function with optional synchronism and voltage check logic is compatible with a variety of reclosing practices. Sequence coordination logic allows coordination with downstream reclosers.
acSELerator QuickSet® SEL-5030 Software
Develop settings offline, and download them to the recloser. QuickSet Software automatically checks interrelated settings and highlights out-of-range settings.
SEL Fast Sequential Events Recorder (SER)
Transfer unsolicited binary fast sequential events recorder (SER) data with time stamps, along with settings and other data, over a single communications link.
Relay- and Recloser-Compatible Time-Overcurrent Protection
The included U.S. (IEEE) and IEC relay curves, user-programmable curves, and all traditional recloser curves maximize recloser control flexibility and coordination. Constant time adder, vertical multiplier, and minimum response time functions improve flexibility. Optionally, create custom curves for the SEL-351R with the SEL-5804 Curve Designer Software.
Large Display and Operator Controls
Large front-panel display and programmable operator control interface pushbuttons make it easy to control your reclosers. Control interface pushbuttons include a "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.
The lightweight painted aluminum cabinet exhibits the same outstanding resistance to corrosion as a stainless steel cabinet and is easy to install.
Extra Cabinet Space
The cabinet accommodates 16 Ah batteries with additional space inside the recloser control enclosure to add communications equipment, such as a cellular modem and point-to-point radio, to integrate the recloser control into your distribution automation system.
Advanced 24 Vdc Battery-Charging and -Monitoring System
The SEL-351R includes a 120 Vac-powered battery charging system that monitors and tests the 24 Vdc battery, and comes with an automatic sleep and local wake-up function. A 12 Vdc battery is available for powering modems and radio communications equipment (6 W continuous, 13 W for 1 second).
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
Mirrored Bits communications technology increases the flexibility of relay-to-relay logic communications schemes for improved feeder performance.
