Basic parameter of fuse holder are size ,current, voltage,number of poles,with LED indicator or without LED indicator . Size are 10*38,14*51,22*58. Generally current for fuse holder are 32A ,which refer to 10*38 fuse holder , 63A refers to 14*51 fuse holder , 125A refers to 22*58 fuse holder. Voltage can be devided into AC voltage and DC voltage. Generally AC voltage are 400V and 690V , DC voltage are DC 48V and DC 1000V. Number of poles can be 1 Pole,2 Pole, 3 Pole,1 pole+N pole , 2 pole+ N pole , 3 pole +N pole. LED lamp will light up when the fuse blown out,which can help indicate the switch in trouble quickly. But you also can choose the one without LED indicator.
Knife switch is generally used to control the ON/OFF of AC or DC low voltage (not more than 500V) circuits. Under the rated voltage, its working current cannot exceed the rated current. When we choose knife switch to control the machine’s power supply, the knife switch is mainly used as a power switch,which do not need to be cut off or closed frequently.Generally,it is not to switch on or cut off the working current of the motor and .There are single pole, double pole and three pole. The three pole knife switch current has 100 A, 200 A, 400A, 630 A and 1000 A .With model no. HD(disconnector switch ) and HS(changeover switch ) and other series.
Automatic transfer switch (ATSE) is a combination of switch and logic thinking, Realize the automatic transfer switch of electromechanical integration. With voltage detection, communication interface Electrical and mechanical interlocking and other functions can realize automatic, manual, remote control and emergency manual Control. It is applicable to automatic conversion of main power supply and standby power supply of power supply system or two loads Automatic conversion and safety isolation of equipment. The operation is to manage the operation of the motor and gearbox with various logic commands by the logic controller The motor drives the energy storage spring to release the acceleration mechanism quickly and Break the circuit and conduct circuit conversion, realize electrical isolation through obvious visible state, and greatly Which improves the electrical and mechanical properties.
