ABB REF542PLUS Feeder terminal.The feeder terminal REF 542plus integrates measurement, monitoring, protection, control and self-diagnosis functions into a single device. With its integrated communication protocol, the REF 542plus can be easily integrated into any substation automation system from ABB or a third party.

The ABB REF542plus feeder terminal is a powerful digital device specifically designed for medium voltage applications, such as feeders, transformers, and motor protection. It packs measurement, monitoring, protection, control, and self-diagnosis all into a single unit, making it much more useful than its predecessor, the REF542. This new generation of equipment can support integrated communication protocols and can be easily connected to ABB or other third party substation automation systems. The REF542plus works with ABB's main air - and gas-insulated switchgear solutions, as well as versatile software to help make it more adaptable and perform better in a variety of operating environments.
