Circuit breakers are important devices that interrupt current when an electrical fault occurs. If they fail to operate properly during a fault condition, the electrical system can be at risk of being damaged. Additionally, the mis-operation of such a device can lead to costly impacts associated with the interruption of electrical service. Technicians should regularly test for potential problems so the circuit breakers can be verified to operate according to their intended design. Regular maintenance practices provide the opportunity to identify and correct operational issues and ensure power system reliability.READ MORE >>

Designed to perform secondary injection testing on the Static Trip III (STIII) overcurrent tripping system utilized on the RL breaker, the Siemens PTS-5 Secondary Injection Test Set, packaged in a self-contained case, contains a microprocessor controlled constant current source which enables rapid verification of the performance of the STIII.
Directly enter the desired test current on the numeric keypad for easy test configuration, and the self-contained, automatically controlled digital timer allows simple verification of the time-current tripping characteristics. The Siemens PTS-5 also provides a regulated DC voltage to allow functional testing of the tripping actuator.READ MORE >>
Circuit breakers are used in homes, office buildings, and electric facilities. These instruments are prone to break down as they gather moisture, contaminants, and dirt while in use. If not maintained regularly, ciruit breakers insulation becomes weak as a result of the heat that is created due to arc interruption. Chemicals like hydrogen sulphide or chlorine can also be major factors in the damage and corrosion of insulation as well as metal components of circuit breakers.READ MORE >>
