Siemens PTS-4: Secondary Injection Test Kit

Siemens PTS-4
Secondary Injection Test Kit, StaticTrip I, II, III

Siemens Energy & Automation portable test set type PTS-4 is designed for testing the static overcurrent tripping systems used on the LA and RL line of low voltage power circuit breakers. It provides a means of testing the magnetic tripping actuator as well as the static trip device. The portable test set, using power from an ordinary 120 volt convenience outlet, can provide circuit breaker testing equivalent to much more expensive and cumbersome primary current testing.
