*KC800-1 series current selection table
Specification | Current range | Motor power | Remark: 1,choose protectors specifications must be based on motor power and decide (selection table according to the motor power is AC380V). 2,voltage specification for AC220V and AC380V,to control the motor secondary circuit voltage and decide . 3,specification for 300A,400A,500A,600A and 800A protector .must add three change for 5A than the current transformer . 4,the three change for 1A transformer in order to quote . |
10A | 1~10A | 1~5KW | |
50A | 5~50A | 4~25KW | |
100A | 10~100A | 20~50KW | |
200A | 20~200A | 50~90KW | |
300A | 50~300A | 75~150KW | |
400A | 100~400A | 100~200KW | |
500A | 150~500A | 130~250KW | |
600A | 200~200A | 150~300KW | |
800A | 300~800A | 200~400KW |
*KC800-2 series rated current chosen table
once current specifications(A) | 2 | 6.3 | 25 | 63 | 100 | 200 | 300 |
Applicable scop of current (A) | 0.5~2 | 1.5~6.3 | 5.0~25 | 20~63 | 20~100 | 80~200 | 150~400 |
Note :100A of them and the low specification takesΦ16 current transformer , 200~300A specification takesΦ30 current transformer ,such as X-100/MTU ,X-200A/MTU.
Secondary current specification(A) | 200/5 | 300/5 | 400/5 | 500/5 | 600/5 | 800/5 |
Applicable scop of current (A) | 80~200 | 150~300 | 200~400 | 250~500 | 300~600 | 400~800 |
NOTE :Secondary current tested all take Φ16 current transformer ,the customer should be indicated in order A current transformer is N:1 or N:5 ,didn’t indicate when the factory for N:5A
EX 1:X-300/5/MTU(N:5);EX 2:X-300/1/MTU(N:1)
