Item No.: CO3301-4D

Time Overcurrent Relay with directional feature

Training panel with digital overload and short-circuit protection for electrical machines and cables in meshed networks (ANSI 50/ 51 and 67). The relay parameters can be set manually or in conjunction with a PC.

  • Nominal current: IN=1A

  • Un: 400V

  • Nominal frequency: 50-60Hz

  • Setting ranges:
    I>: 0.5-2.0x I
    N/tI>: 0-100s
    I>>: 1-15x I
    N/t>I>: 0-2.5s

  • Tripping characteristics:
    - normal inverse
    - very inverse
    - extremely inverse
    - independent

  • Inputs/outputs: 4mm safety sockets

  • The integrated interface RS 485 is suitable for setting the relay parameters. It is also possible to store and transmit measured relay values to and from the PC. Optical signal transmission guarantees galvanic isolation.

  • Dimensions: 297 x 456 x 125mm (HxWxD)

  • Weight: 1.8kg
