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.

Professional Line

The digital single-function or multi-function relays from SEG Electronics provide all common protection functions for low and medium voltage applications and are designed for DIN rail mounting.

Rated voltage and frequency can be set by means of DIP switches; pick-up values and tripping delays via potentiometers.

The wide-range power supply for AC and DC make the relays universal.

An optionally available interface adapter enables the devices to communicate with the Windows ® PC software Smart view.

WI Line

All relays from the WI Line are self-powered time overcurrent relays, which means they take their energy from the current transformers.

Since they do not require auxiliary power, the WI Line relays are well suited for use in self-sustaining transfer and distribution stations, local grids, and ring-main-units.

Tripping characteristics range from two-stage, independent (DEFT) and dependent (INV) time-overcurrent protection, up to special characteristic curves. As further options, we offer some relays with integrated earth fault protection.

SEG Electronics has also developed serial products, which match nearly any circuit breaker commonly available on the market. The electronic parts of the relays are completely sealed in, making the relays resistant to even the very worst environmental influences.
