Rơ le bảo vệ, Model: SEL-710 của Hãng: SEL   SEL-710 Motor Protection Relay

Optimize Start Times
The SEL-710 calculates thermal energy in the motor to determine maximum safe start times, with full motor protection. Accurate temperature tracking also minimizes the time needed between starts.

Convenient Controls
Use the four programmable pushbuttons on the front panel for quick personalized control, with factory default start and stop functions.

Advanced Protection
The SEL-710 provides protection for overcurrent, thermal overload, undercurrent, current unbalance, current differential, phase loss, ground fault, and over- or underfrequency, and much more.

Easy Communications
Choose from single or dual, copper or fiber-optic Ethernet as well as Modbus TCP, IEC 61850, Modbus Serial, EIA-232, EIA-485, Telnet, and File Transfer Protocol (FTP) communications. Pick one or multiple connections, including multiple Modbus sessions for custom configuration of your application.

Rugged Design
Trust the industry’s widest ambient operating temperature range, –40° to +85°C (–40° to +185°F). The SEL-710 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. A conformal-coating option for the printed circuit boards provides an additional barrier to airborne contaminants, such as hydrogen sulfide, chlorine, salt, and moisture. In addition, the SEL-710 is ATEX- and Underwriters Laboratories (UL) Class I, Division 2-certified for use in hazardous and potentially explosive environments.
