IEC 60947-1 Circuit Breaker Tripping Characteristics Comprehensive Testing Machine
Product Information For Circuit Breaker Tripping Characteristics Comprehensive Testing Machine:
The test equipment is designed and manufactured according to the standard requirements of
IEC60898-1 clause 9.10, IEC60947-1 clause 7.2.1 and etc.
It is made to verify that the circuit-breaker complies with the requirements, which apply 1.13 times, 1.45 times, and 2.55 times the rated current to test to see if it trips within the specified time. The test equipment can also test the instantaneous tripping characteristics of the circuit breaker, that is, apply 3 to 10 times the rated current for the test whether it jumps out of the time. It is suitable for online testing of molded case circuit breakers and miniature circuit breakers before leaving the factory. It is a necessary equipment for electrical performance testing of circuit breaker manufacturers.

Equipment characteristics For Circuit Breaker Tripping Characteristics Comprehensive Testing Machine:
The equipment chamber is welded with high-quality steel, the plate is sprayed and sealed, and the surface is anti-static, anti-rust, and anti-corrosion sprayed. The upper part of the equipment is equipped with a panel, a power switch, and a variety of wire ends (for delay tripping test). The equipment is reasonably designed and used with the advantages of convenience, simple operation, reliable performance and beautiful appearance.
Test principle For Circuit Breaker Tripping Characteristics Comprehensive Testing Machine:
This test equipment adopts the principle of low voltage and high current output, uses the large current in the machine to isolate the output current of the transformer, sets the current size through the touch screen, and the constant current source adjusts the size of the output current of the transformer, which has the function of automatically stabilizing the current. Set the test time through the touch screen display and compare the test trip time to judge the quality of the circuit breaker.
