Product Overview
The T Series thermal motor protectors are designed as temperature limiters and thermal cut-outs for a variety of applications including motors, transformers, coils, and electronics. They offer both temperature and current sensitivity or temperature sensitivity only, with a focus on small dimensions and high power ratings. These devices are suitable for use in protection categories I and II and are resistant to impregnation with ordinary resins and lacquers.
