Harmony Relay. Semiconductor relay for mounting on a top hat rail with aluminum heat sink. The load circuit is designed for 3-phase networks in the range of 48-600 VAC and 25 A can be switched per phase. The switching behavior is instantaneous switching and corresponds to 3 make contacts. The control voltage is 4-32 VDC and switches all phases. An LED display provides information about the control. The connection is made with screw terminals. Width 88 mm.
