RM17TU00 Mains monitoring, phase sequence, phase failure, undervoltage

Harmony Control. This mains monitoring relay monitors three-phase networks for phase sequence, phase failure and undervoltage (2 - 20%). A relay changeover with a load capacity of up to 5 A is provided for signalling. In the event of phase faults, the output drops out without delay. In the event of undervoltage, a switch-off delay can be set. The settings are made via the control elements on the front, which can be protected against modifications under a transparent cover. Two LEDs indicate the status. The overall width is 17.5 mm, and mounting is on the DIN rail. Supply from the measuring circuit 208 - 480 V AC (50 - 60 Hz).
