WD Series DIN rail-mounted protective relays incorporate features that allow a single relay to be configured to several different sensing voltages, currents, and frequencies, the company says. For example, the WD2759 voltage relay can be used in 120-, 208-, 277-, or 480-V single- or three-phase systems, and has built-in under- and over-voltage trip settings and adjustable time delays. The unit can therefore replace multiple relays. The series is also available in three control voltages, to ensure compatibility with modern design, says the company.
