Yokogawa CTW Clamp-on Current Transformers


Clamp-on Current Transformer


Availability: 3 in stock

The Yokogawa CTW Series are clamp-on current transformers that can be installed much easier than conventional current transformers, thereby saving installation costs. These transformers are particularly useful when expanding an existing system since you can attach them to a cable without cutting it. The standard lineup includes 100 A, 200 A, 500 A, and 800 A models. Also, compact and lightweight 100 A and 300 A models are available. 

  • Primary/Secondary current value and Rating burden:
    Standard models:
      CTW10: 100 A/1 Arms 50/60 Hz, 0.5 VA
      CTW20: 200 A/1 Arms 50/60 Hz, 0.5 VA
      CTW100: 500 A/5 Arms 50/60 Hz, 2.5 VA
      CTW130: 800 A/5 Arms 50/60 Hz, 2.5 VA
    Compact and light-weight models:
      CTW15: 100 A/1 Arms 50/60 Hz, 0.3 VA
      CTW35: 300 A/1 Arms 50/60 Hz, 0.5 VA
  • Accuracy & Linearity:
    Within ±1.0% of Full Scale
  • Operating circuit voltage:
    Within 500 VAC
  • The clamp-on type makes the installation much easier for both existing and newly-established systems.
  • Being able to fix the transformer to the power line directly enables users to select the installing point comparatively freely.
  • The CTW series contains a device for suppressing hazardous voltages that may arise when the second line is open-circuited. It prevents burnout or outage.
