Technological process: materials→Molding→screw tap→electroplate→electro welding→riveting→testing→packing
Through years of focusing on the actual system operation and customer’s needs for new
energy at home and abroad, the new type SRM3 has come out.
SRM3- (HU) series mold case circuit breaker, the rated voltage up to AC1000V, current up to 400A.
Compliance with standards
IEC 60947-1 GB/T14048 1 General Provisions
The IEC 60947-2 GB/T14048 2 circuit breaker
Apply to the environment
1. The altitude of the installation site should not exceed 2000m.
2. The ability to be affected by humid air (three prevention types);
3. Able to be affected by salt fog and oil fog (three prevention types);
4. Can withstand the influence of mold (three prevention types);
5. In the medium without explosion danger, and the medium is free of gas and conductive dust enough to corrode metal and destroy insulation.
Note: ① Three protection products need special customization, please indicate TH.
The characteristics and accessories of the circuit breaker are set by the manufacturer and can not be adjusted at will in use. Provided the user complies with the conditions of storage and use. The seal of the circuit breaker shall be intact within 24 months from the date of delivery by the manufacturer. The manufacturer shall be responsible for the replacement and repair of the circuit breaker free of charge if the products are damaged or cannot be used normally due to quality problems.
