Product name:

CF8461 Circuit Breaker Instantaneous Trip Characteristics Testing Equipment

Conform to the standard:

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 Article 9.10, GB14048.2-2008 Article 7.2.1, and JB/T8979-2006 Article
8.13. The circuit breaker can be tested for delay tripping characteristics, that is, applying 1.13 times, 1.45 times, and 2.55
times of the rated current to test whether it trips within the specified time; It can also carry out the instantaneous trip
characteristic test of the circuit breaker, that is, apply 3~10 times the rated current to test whether it trips within the
specified time.

Scope of application:

It is mainly suitable for DZ series circuit breakers for online pre-factory testing, and can test the instantaneous trip
characteristics of circuit breakers, and the equipment has the functions of rapid product installation, automatic testing and
automatic judgment. It is a necessary equipment for the electrical performance testing of miniature circuit breaker manufacturers.
