Features

  • Developed with the same outline dimensions for the 630AF to 1600AF of draw-out type, making it even more compact the previous products.
    Now 49% in weight and 48% in volume compared to the previous product. Can be mounted in a switch board compartment of 400mm width, height and depth.
  • The direction of rear connection terminals (horizontal, vertical) can be changed by the customer.
  • Quick connection terminals are used for control circuit terminals. Eliminates the need to tighten screws with a screwdriver, making connection work much faster.
  • Standard type and Smart type of Over-current Release (OCR) are available depends on the application.
  • Includes a measurement function for circuit information, in addition to protection functions.
    If equipped with an optional communication module, various types of circuit information can be remotely monitored and managed by measurement data.
  • Measurement accuracy has been significantly improved compared to the previous product, with reading accuracy that complies with the IEC61557-12 international standard.
    This ensures a high level of accuracy, with ±0.5% for current and voltage measurements, and ±1% for active power measurements.
  • Connectiing the TemView PRO remote display with the TemPower PRO using the special cable and mounting it on the switchboard panel allows the smart type OCR measurement value to be checked using the panel.
  • Rated current of 2000A is available for Fixed type.
