| High Light | circuit breaker testing machine ，delayed tripping characteristic tester ，instantaneous tripping test equipment | ||
I. Compliance with standards:
The performance of the miniature circuit breaker tripping characteristic testing machine is designed and manufactured in accordance with the national standards of GB10963.1-2005, GB14048.2-2008, and JB/T8979-2006, Article 8.13. It is capable of conducting delayed tripping characteristic tests on circuit breakers, that is, applying 1.13 times, 1.45 times, and 2.55 times the rated current for tests to determine if they trip within the specified time. It is also possible to conduct instantaneous tripping characteristic tests on circuit breakers, that is, to apply 3 to 10 times the rated current for the test and determine whether it trips within the specified time.
Ii. Scope of Application
It is mainly applicable to the online pre-factory detection of DZ series circuit breakers, capable of conducting instantaneous tripping characteristic tests on circuit breakers. The equipment features rapid product installation, automatic testing, and automatic judgment functions. It is an essential device for the electrical performance testing of miniature circuit breaker manufacturers.
