1000V DC 1A 2A to 20A fuse module
1, Fuse Module Specifications
SGR 1000V DC 1A 12A fuse for solar system
1. PV system:DC Fuse
2. Rared Voltage:DC 250v to 1000V
3: IEC66143-1 & EN61643-II
4, Rated current:1A, 2A, 3A,4A,5A, 6A,8A, 10A, 12A, 15A, 16A, 20A
Fuse selection method
1) Determine the type of fuse according to the conditions of use.
2) When selecting the fuse specifications, you should first select the specifications of the melt, and then select the fuse according to the melt specifications.
3) The protection characteristics of the fuse should be protected with the object of the overload characteristics of a good match.
4) in the distribution system, the fuse should match each other, the general level of the rated current of the melt than the next level of the rated current of the melt 2 to 3 times.
5) For the protection of the motor fuse, should pay attention to the impact of motor starting current, the fuse is generally only as a motor short circuit protection, overload protection should be used thermal relay.
6) The rated current of the fuse shall be not less than the rated current of the melt; the rated breaking capacity shall be greater than the maximum short circuit current that may occur in the circuit
3, Product Parameter
Rated breaking capacity
4, The main drawbacks and weaknesses of the fuse
① after the fuse must be replaced fuse fuse;
② protection function is single, only one overcurrent inverse time characteristics, overload, short circuit and ground fault are used this protection;
③ the occurrence of a phase fuse, the three-phase motor will lead to the adverse consequences of the two-phase operation, of course, can be used to send the alarm signal to make up the fuse, a phase fuse can be disconnected three-phase;
④ can not achieve remote control, need to switch with the electric knife, switch combinations are possible.
5, The main advantages of fuses
A, Good selectivity Up and down fuse fuse rated current as long as the GB and IEC standards to meet the requirements of the overcurrent ratio of 1.6: 1 requirements, that is, the upper rated fuse current is not less than the subordinate of the value of 1.6 times, as the upper and lower level Selective cut off fault current;
B, Good current limiting characteristics, high breaking capacity;
C, Relatively small size;
D, Cheaper prices.
