Product Description

ABB VHXM23B Static Protection Relay

ABB VHXM23B Static Protection Relay - Over voltage relay with variable time delay

The relay type VHXm is a static under/over voltage relay used for detection of under voltage (or loss of voltage) or over voltage in the AC system. Relay is used for over voltage protection and supervision in distribution systems. Relay is also used for overvoltage / undervoltage protection of Generators, Motors and Transformers.

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.

Design and principle
The VHXm is a AC voltage measuring relay. Different versions are available for a) Fixed voltage setting with instantaneous operation b) Variable voltage setting with or without variable time delayed operation. The AC voltage to be measured is applied at terminal 3 and 4. The input voltage is isolated, scaled and suitably conditioned for measurement.

Operating voltage level and time delay can be set with the potentiometer on the front-panel of the relay.
The product of the potentiometer setting and multiplier (marked) is the set operate time for relay.
The VHXm is powered by a DC auxiliary supply. The relay has a built-in electro-mechanical output relay providing medium duty contacts. The output relay also has one red hand reset flag. The relay is available in draw-out type flush
mounting model.
