The Siemens TD500 is a secondary injection test set specifically designed to test Siemens 3VA molded case circuit breakers with ETU (Electronic Trip Unit) trip units.
This means it’s used to verify the proper operation of the electronic trip units that protect these circuit breakers. These ETUs can have various trip functions, and the TD500 is capable of testing them.

Testing:
- Overcurrent: Tests the trip unit’s response to overcurrent conditions, ensuring it trips within the specified time-current characteristics.
- Undervoltage: Checks the trip unit’s ability to trip when the voltage drops below a certain threshold.
- Earth Fault: Verifies the earth fault protection function, which detects and trips on ground faults.
- Phase Sequence: Tests the trip unit’s response to incorrect phase sequence.
- Trip Curve: Allows for detailed testing of the trip unit’s time-current curve to ensure it matches the specifications.
- Trip Time: Measures the actual trip time of the breaker under various fault conditions.
Features:
- Portable and easy to use
- Built-in display for test results
- Can be connected to a PC for data logging and analysis
- Test functions: overcurrent, undervoltage, earth fault, phase sequence, trip curve, trip time
