DDA-1600,
DDA-3000, DDA-6000
Circuit Breaker Test Sets
- Digital signal processing
technology.
- Variable firing angle and pulse
duration.
- Compliant with NEMA AB-4 test
guidelines.
DDA test sets
incorporate the DDA-1 Digital Data Acquisition Instrumentation
and Control System providing increased control of output
current and high accuracy metering of the breaker under test.
Universal in application, the DDA test sets will test
virtually all low-voltage, molded-case and metal-clad,
direct-acting ac circuit breakers rated up to 1600 through
6000-ampere frame size. The test sets also may be used for
other high-current applications such as verifying the ratio of
current transformers, testing thermal or magnetic motor
overload relays, and performing heat runs or primary injection
testing of high-voltage breakers and their associated
protective relays.
