HighTECH Line
The modular protection devices from SEG Electronics for low voltage, medium voltage, and lower high voltage level have numerous and complex protection functions. The protection range includes basic time overcurrent protection, machine protection and high-grade differential protection.
In addition to relays with single protection functions, available are also multi-function protection. Devices are designed for door mounting, either in separate housings or in 19“ racks. For back panel mounting, an adapter is also available.
Thanks to our “plug-in” technology with automatic short-circuit mechanism for the current inputs, these relays can be changed during operation. LEDs and an alpha-numerical display show clear text indication of measuring, setting and fault values, and allow intuitive operation. Coupling to your SCADA system is achieved via the standardized interface.
