Power Circuit Breakers

for safety and protection


We hear you!

We have asked registered users for their feedback on the TemCurve Lite software. Some people complained that it was difficult to download.

We have removed the registration form from TemCurve Lite download. You may now download it without registration.

Overall we received positive feedback with some good suggestions which we will take in to account.

For those of you who would like to receive Terasaki updates we have added a registration form on our news page. Subscribe and be the first to receive our news.
