Product lines - Professional Line

The digital separate or combined 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.
