  • Nr steps: 1
  • Input current: .../250 mA
  • Switching unit: Contactor

INFORMATION

Description

The DIR2 Power Factor Relay is capable of acting on a circuit in accordance with the reactive inductive or capacitive current transmitted through it. The DIR2 relay measures reactive current in mA of the secondary of a .../250 mA current transformer MC1 or MC3 type. The front of the relay has a control panel that is used to adjust the reactive current where the relay will act. It has a LED that indicates the status of the relay.

Applications

The DIR2 relay is easy to install and program, making it the best solution in the following applications:

  • Individual compensation of small, medium or large power loads.
  • Partial compensation in installations with automatic equipment available.
  • Partial or total regulator in low-power installations.Instantaneous and total disconnection of capacitor banks when there is a high capacitive current in the network.
  • Control of reactive currents- capacitive and inductive - triggering an alarm signal when a high current is detected.
