Alongside relays with single protection functions, relays with combined protection functions are available. 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 their “plug-in” technology with automatic short-circuit mechanism for the current inputs, the 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. By means of the standardised interface, coupling to your SCADA system can be achieved.
