UPA-16 (UPA-20) | Circuit breaker tester | Circuit Breaker Test Set

Mobile systems for primary injection testing and trip curve control of circuit breakers and overcurrent protection relays.

ACCURATE TRIP CURVE CHARACTERISTICS
Testing circuit breakers with real sine-wave current (when using external voltage regulator) yields reliable results of the primary current injection.

TESTING ANY TYPE OF BREAKERS
The system allows to obtain trip curves of circuit breakers fitted with electromagnetic, thermal and electronic trip elements.

FULL STANDARD COMPLIANCE
Systems UPA-16 and UPA-20 can perform fixed-duration current injection tests, thus allowing to carry out all test types specified by IEC 60898-1.

HIGHLY-EFFICIENT CURRENT SOURCE
This system is equipped with a current source based on a toroidal transformer, featuring optimal thermal performance and relatively low energy consumption.

MOBILE FORM FACTOR
All modules and accessories making up the system are conveniently mounted on a special trolley, which eases transportation and significantly simplifies the work of an operator.
