The CTW Series are clamp-on current transformers that can be installed much easier than conventional current transformers, whereby saving installation cost. These transformers are particularly useful when expanding existing system since you can attach them to a cable without having to cut it. Standard lineup includes 100 A, 200 A, 500 A and 800 A models. Also compact and light-weight 100 A and 300 A models are available. Primary/Secondary current value and Rating burden: CTW100: 500 A/5 Arms 50/60 Hz, 2.5 VA
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
