What is the difference between a normal circuit breaker and a smart circuit breaker?

The ordinary circuit breaker relies on the deformation of the bimetal and the magnetic field force for overload and short circuit protection, and the intelligent circuit breaker collects the current of each phase through the transformer, compares with the set value by the microprocessor, and then issues an instruction to drive the electronic trip unit. The mechanism tripped.

Ordinary circuit breakers have less accurate action values ​​and are susceptible to environmental influences. Derating should be considered when using them. The intelligent action values ​​are more accurate and less susceptible to environmental influences.

Ordinary circuit breaker setting current is generally not freely adjustable (some new products can adjust the instantaneous multiplier and overload action value), while the intelligent circuit breaker can be adjusted in several steps, and even some can be continuously adjusted in steps of 1A.

Ordinary circuit breakers generally only provide two-stage protection, while the intelligent ones can provide three-stage protection, and some also have functions such as pre-alarm, grounding protection, and phase loss protection. In addition, by adding a communication module, it is possible to communicate with the host computer.

Since the smart circuit breaker uses more electronic components, its withstand voltage is lower. Moreover, smart circuit breakers are not allowed to pour into the line.

Infinite distance: remote remote power off, where is the hand ji, where is the electricity, can also control the power abroad

Timed hand ji remote control, for example: returning from work, regularly open the house water heater, take a hot bath

Start and stop information: real-time view of circuit breaker switch status and operation record on hand ji

Hand ji alarm: short circuit alarm, for example: power peak period, short circuit in the house promptly send a hand ji notice to remind the administrator to deal with
