What is the overview of electronic circuit breaker technology?

Date | 2022-08-15 10:06:36

The electronic circuit breaker is a new generation of intelligent circuit breakers developed using excellent design and manufacturing enterprise technology. Rated isolation voltage 400V, suitable for AC 50Hz, rated working voltage up to 400V, rated current up to 800A, infrequent motor switching and infrequent starting.

Based on Chinese digital electronic product technology, the electronic circuit breaker combines electronic decoupling devices with the intelligent development of advanced science and technology, with faster decoupling speed, higher environmental protection accuracy and higher reliability. The wide range of rectification can make it easier for the system to carry out continuous structural upgrade development. Thanks to the excellent computational thinking analysis of the processor and patented transformer technology, the use of these social functions can improve the provision of measurement information and operating cost management services. Users can effectively avoid or deal more efficiently with the risk of interference with the control system and monitor the operation of the system more proactively.

Protection function set by setting adjustment knob

Overload protection: Long delay protection (IR)

The overload protection is an inverse time characteristic, the overload protection operating current value Ir is adjustable, the overload protection technical action development time Tr is adjustable.

Short-circuit short-delay protection

Short-circuit short-delay current value ISD adjustable, delay time adjustable Circuit breaker trips after a very short delay, can be used for selective coordination with lower circuit breakers (class B can be closed)

Short-circuit momentary protection

Instantaneous short-circuit for protection with adjustable operating current value
