Linergy thermal magnetic circuit protectors are a trip free device. These circuit protectors cab be mounted on 35 mm DIN track or Square D terminal block track. The family has circuit protectors with current ratings from 0.1 to 15 A. This circuit protector has a current rating of 5.0 amperes. The thermal feature trips when there is an overload of ten times rated current or less. The magnetic mechanism trips instantaneously when there is a short circuit. Maximum rating of 200 A, but not exceeding 10,000% (100 times) rated current.
