Posted by Protec Tech Team on

Siemens_PTS-4.jpgTest Static Trip I, II, & III trip units used on the LA and RL line of low voltage power circuit  breakers with the Siemens PTS-4 (PTS4) Secondary Injection Test Set.

The test set provides a means of testing the magnetic tripping  actuator as well as the trip unit. 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. 

With the  Siemens PTS-4, Static Trip III trip devices can be tested by themselves, or on a circuit breaker outside the cubicle, or inside the cubicle with the breaker in the TEST or DISCONNECTED position.A circuit breaker is provided in the PTS4 test set to prevent thermal damage from repeated high current tests.

Siemens PTS-4 (PTS4) Secondary Injection Test Set features: 

Input power - 120 Volts, 50 or 60 Hz, 15 Amps maximum
Output - 0 to 120 Volts, 15 Amps Maximum
Maximum continuous current on high scale 1.0 Amps
Maximum continuous current on low scale 0.75 Amps
DC output for actuator test - 0 to 22 Volts Open Circuit
