When the  products need store for a long time,not control the product store environment ,the metal and paint coat will be corroded.So take care: Products must store with room temperature and dry environment .Sealing when under high humidity environment.
Don't store the products with acid volatile liquid and acid gas together.Don't store in high dust environment.
Don't store the products in high temperature and humidity or lowest temperature for a long time ,please install and use as soon as possible.
Don't contact the link wire before products used normally,preventing corrosion from pre-contacting.
Please inform and operate under the manufacturer' advise referring to special store environment such as high temperature and humidity,islands near equator,ultra-low temperature area.

Operation principle 
Each phase of conductor at the Circuit Breaker passes through the zero-sequence current transformer, and the secondary side of coil connects with the electromagnetic tripper. Under normal condition, the vector sum of each phase of current passing through zero-sequence current transformer is zero. The flux of the zero-sequence current transformer is zero. And the secondary output voltage is zero and the circuit breaker doesn`t zreo, and the zero-sequence current transformer would produce the magnetic flux, and the secondary side of coil would output the voltage. Once the leak current increases to drive the output voltage at the secondary side to grow to certain level, the electromagnetic release would activate to drive the operation mechanism to act to break the contact that connects the power, finally to realize the leak protection.
