Time-delay devices for undervoltage releases
Undervoltage releases can also be equipped with external, electronic time-delay control devices which prevent unintentional tripping in response to brief voltage dips during periods of disrupted operation.
Time-delay device for UVR with fixed delay setting
The simple time-delay device with fixed delay setting is available for the following voltages:
110 V and 230 V AC
24 V DC
The delay time setting is 100 - 200 ms.
The device can be screw-mounted or attached to a 35 mm DIN rail.
