Siemens Current Monitoring Relay, 1 Phase, SPDT, DIN Rail - 3UG4621-1AW30

Single Phase Current Monitoring Relay. Current monitoring relays to monitor single phase AC currents and DC currents against the set threshold value for undershoot and overshoot. A current monitoring relay can differ with their measuring ranges and supply voltage types. Features and Benefits. Real effective value measurement Applicable for frequencies with 40-500Hz AC and DC All devices can be digitally set and have an LCD display, a fault memory can be switched on Simultaneous monitoring of overcurrent and undercurrent over the complete measuring range Supply voltage 24-240Vac/dc Starting by-pass time 0.1 -20 secs. Off delay 0.1 - 20 secs. Contacts 1 C/O. Product Application Information. Overcurrent and undercurrent monitoring. Monitoring the functionality of electrical loads. Open-circuit monitoring. Threshold switch for analog signals from 4 mA to 20 mA
