TYP

X72DS

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
Va.c./d.c. (5VA/5W) 20÷60V; 80÷260V

DESCRIPTION

The X72DS series earth leakage relays are designed to 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 the defective system.
In addition to the trip contacts (doubled for a greater application flexibility), it is also availa-ble an alarm contact, useful to indicate the needing of apreventive maintenance in order to avoid unexpected power breaks.
Main features and functions:

  • Wide range of trip currents and delays to guarantee the necessary selectivity in order to keep in operation the parts of the system not involved in thefault.
  • Three ranges of tripping current and two of delay to increase the setting accuracy.
  • Alarm contact settable to 30 or 60% of the trip current.
  • Continuous check of the good connection with the toroidal transformer, performed on the measuring winding, with trip action in case of negative result. • Selectable manual or automatic reset. • Inputs for remote reset.
