Trip/close Module

Manufacturing for this product has been discontinued. Please contact us to discuss alternatives.

MiCOM Alstom P891 is suitable for application with protection relays where relay independent tripping and closing functionality is desired. Independent circuit breaker indication is provided by two LEDS allowing for direct wiring of the circuit breaker's 52A and 52B contacts. With a wide voltage supply range capability, integration into any battery supply system is simple.

Configure the module to integrate with feeder management relay functions such as autoreclosing and check synchronising and provide a secure CB control solution.

Pushbutton covers are provided to prevent inadvertent operation of pushbutton switches. This safety feature allows the module to be used under the most stringent operating procedures. These covers can also be removed if not required.

Key benefits:

  • Control to suit customers' operational procedures
  • Simple and robust design
  • Clear status indication
