The Yokogawa CTW35 Clamp-on Current Transformer, 300 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 CTW35 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 transformers to power lines directly enables users to select installing point comparatively and freely
