Yokogawa CTW-20 [CTW20] Calmp-On Current Transformer, 200 A/1 Arms 50/60 Hz, 0.5 VA

The Yokogawa CTW20 Calmp-on Current Transformer, 200 A/1 Arms 50/60 Hz, 0.5 VA can be installed much easier than conventional current transformers, whereby saving installation cost. This transformer is particularly useful when expanding existing system since you can attach it to a cable without having to cut it. Also compact and light-weight, the CTW20 contains a built-in device for suppressing hazardous voltages that prevents a burnout or outage at the open-circuit of secondary line.

Features:

• Clamp-on type makes installation much easier
• For use with both existing and newly-established systems
• Fixing transformer to power line directly enables users to select installing point comparatively and freely
• For use with suppressing hazardous voltages that may arise when secondary line is open-circuited and

      prevents burnout or outage
