Relays and control elements

WI/020-30

WI/020-30, Current relay

Code: P32013.

  • Trip time (adjustable): 0,5 … 30 s
  • Margin of setting (adjustable): 2 ... 20 A

INFORMATION

Description

The WI current detectors are electronic devices with an output relay that is connected or disconnected, in accordance with the level of current detected in the circuit.

  • The trip level is adjusted with the potentiometer on the front of the unit.
  • The reset process is automatic with currents under 10% of the trip level (Hysteresis).
  • Delay: the connection and disconnection times of the output relay can be adjusted separately.
  • Measurement of the current, depending on the type:
    • With built-in current transformer (net diameter ∅ 25 mm)
    • Separate transformer, input.../5 A ~

Applications

WI's can be used in any application that needs to control the load:

  • Power supply units for grinders or aggregate grinding units.
  • Loads in extrusion machines
  • Pump control
  • Load on motors, etc.
