Characteristics to be specified
Aux. supply voltage Standard Va.c. (±10%, 45÷65Hz, 3VA) 115 - 230 V
On demand
with extraprice		 Va.c. (±10%, 45÷65Hz, 3VA) 115 - 230 V 24V; 48V; 400V
Vd.c. (-15...+20%, 3W) 24V; 48V; 110V; 220V

DESCRIPTION

The X...DD series earth leakage relays are designedto measure the leakage or unbalance currents caused by conductors or appliances insulation losses and to react, in case the set limits are exceeded, switching off the power supply to thedefective system. Thanks to their distinctive feature (the displaying of the leakage current) it is possible to continuously monitor the insulation state and to program the preventive maintenance in order to avoid unexpected power breaks. Main features:

  • Continuous digital displaying of the instantaneous leakage current from 0,02A to 10.0A.
  • Setting of the operating parameters (current and time) independently for alarm and trip.
  • Continuous check of the good connection with the toroidal transformer performed on the measure winding, with displaying of a warning message in case of negative result and swit-ching of the alarm and/or trip contacts (programmable).
  • Memorizing (even in case of power supply losses) ofthe maximum fault current.
  • Operation (enable or disable) of the “TEST” key programmable.
  • Manual reset or automatic reset in 2 seconds (with disabling of the automatic function after the third trip in less than 9 minutes).
  • Programmable operating mode of the trip contact as impulsive (with pulse width ranging from 100 to 900 msec.) or as steady.
