Product Description

ABB IRXm Static Protection Relay- Circulating Current Relay


ABB IRXm Static Protection high speed restricted earth fault protection relay

ABB IRXm Static Protection relay, the circulating current relay IRXm is mainly used for high-speed restricted earth fault protection of generators and transformer windings. For the selective detection of faults, current transformers in summation connection are employed with an external stabilizing resistor for high impedance method of measurement. The relay is provided with a band-pass filter which suppresses harmonics and DC components of the input current. The relay is suitable for current transformers with secondary rating of both 1A and 5A.

OTHER HIGH SPEED TRIPPING RELAY RX SERIES

  1. RXPSU6n , with 6 free contacts and without operation indicator
  2. RXPSU14n with 14 free contacts and operation indicator
  3. RXPQ8n


FEATURES

  • High degree of reliability, even when it has been idle for a long time
  • RXPSU14n is with mechanical flag type indicator
  • 6 / 14 contacts with double interruption!
  • Contact configuration can be changed with ease
  • Wide range of voltage and contact configuration


APPLICATION

For remote and automatic control there is often a need for contactors which have two stable contact positions, even in the dead state. This requirement is fulfilled by changeover contactors type RXPSU...n. The application of alternate control pulses to the coils because the contacts to change from the one state to the other. If the supply is interrupted, the contacts remain in their previous position, even when the voltage is restored.
