New C45 mcb mini circuit breakers AC, DC optional, upto100A Breaking capacity: 6kA Standard:IEC60898 CEapproval,qualified
FATO MECHANICAL AND ELECTRICAL CO., LTD. is a professional manufacturer of series of circuit breakers in China.
DZ47/C45 series Mini Circuit Breaker (new type)
APPLICATION
The DZ47 series mini circuit breaker can be used for overload and short circuit protection of circuit ,illumination and power equipment in circuit of AC 50Hz or 60Hz with rated voltage for 230/400V rated current to 100A and below. It can also be used for the infrequent on-off changeover for the circuit and equipment under normal conditions.
The product conforms to IEC60898, GB10963 standard.
STRUCTURE FEATURES
This series circuit breaker is composed by plastic enclosure, over-current release, operating mechanism, contact and arc extinguish system etc. The enclosure is injected by high strength, and high flame-resistant plastic .
The multi pole circuit breakers are assembling by many single-pole, the trip is connected with the joint bar, the handle was united with the linkage cover, has guaranteed the uniformity of each make-and-break.
WORKING CONDITION
1. Altitude less than 2000m
2. Ambient atmosphere temperature :-5°C~40°C and the average temperature is not more that 35°C during 24 hours
3. Relative humidity of ambient temperature is less than in 40°C, the humidity can be large under rather lower temperature. The largest monthly average is 90% with the lowest temperature is 25°C. The curd on the appearance should be considered as the temperature changed.
4. Pollution grade 3
5. Mounting category : III
6. Mounting type: Adopts TH35-7.5 type mounting rail.
7. Mounting angle: vertically (mounting panel and ground) , tolerance should be less than 5°
