AC Current, Asymmetry and Contact Monitor ES-USIY314
or 3-phase current monitor, AC Current relay, AC Current sensor, 3-phase current relay, Current asymmetry monitor, current asymmetry relay
- For monitoring of stator currents of induction motors
as well as the contacts of reverse poling contactors - Current relay for rated current range: 0,5 ... 600AW (ampere windings), f = 35...500Hz
- Fault memory and indication for each phase
- Switchable while in operation between AC current and contact sensor
- Fault signalling via 2 relays (1 changer each) and one optocoupler output per phase
- LED’s to display the state of operation
- Mode AC current sensor
- Delayed activation of the fault signallings (adjustable from 0 ... 3.8 sec.)
- Fault signalling with asymmetric currents
(permissable deviation of the phase angle adjustable from 4 ... 34 degrees) - Optionally fault signalling with incorrect phase sequence
- Mode Contact sensor
- Delayed activation of the fault signallings (adjustable from 0 ... 0.5 sec.)
