SEL-351R Recloser Control

The SEL-351R Recloser Control, derived from SEL's premiere distribution relay, the SEL-351 Protection System, 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, while the simple settings and large operator controls make the SEL-351R very user-friendly.

Plug-In Recloser Compatibility—Choose the SEL-351R for traditional 14-pin recloser applications. The control is a plug-compatible replacement for Eaton (Cooper) Form 3, 3A, 4, 4A, 4C, 4D, FXA, FXB, 5, and 6 recloser controls. The SEL-351R is compatible with popular reclosers from ABB (Joslyn), Eaton (Cooper), G&W, and Hawker Siddeley (Whipp & Bourne). Familiar “EZ” recloser control settings speed commissioning of the control.

Automatic Network Reconfiguration—Combine Mirrored Bits communications, directional elements, voltage elements, and SELogic control equations to optimize your solution for Automatic Network Reconfiguration.

Fault Location—Efficiently dispatch line inspection and repair personnel with the built-in fault locator and fault type identification. Identify recurring feeder trouble points to improve reliability.

Coordination—Selectively coordinate with upstream relays and recloser controls using a Mirrored Bits communications link for secure, high-speed fault clearing on distribution circuits. Also, use the oscillographic event report and Sequential Events Recorder (SER) data to measure and improve protection device coordination.
