Product lines - 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.

A detailed overview of the available HighTech Line devices can be found in the HighTECH Line Overview (PDF).
