High-Voltage Limt-Current Fuse For Protection Of Electrical Motor

This product can be used in indoor Ac system of 50Hz rated voltage of 3.6KV, 7.2KV and 12KV. When used together with other protection facilities (such as switches and vacuum contactors), it works to protect high-voltage motor and other electric facilities from overloading and circuit break. 

Note: 1.The aboveid rated parameters for single pipe,the fuses can be parallel connected by fixed structure to geta high rated current.
          2.Sizes in the bracket are for inserting fuses.

◆Basic parameters

Basic parameters: Table 1, Table 2

Table 2

The high-voltage fuse signal indicating device is connected to the high-voltage fuse, and the micro switch on it can monitor the working state of the high-voltage fuse. Using insulated flexible and bendable transmission device, the movement of the fuse striker is transmitted to the micro switch. The micro switch has a pair of AC 25VI5A-normally open and normally closed switching contacts.
The striker end of the device can be installed with a high-voltage spring clamp contact on the connecting plate 1, and the screw hole of this accessory is directly matched with the screw hole of the spring clamp contact of the high-voltage fuse, without additional drilling. The connecting plate 2 can also be used, the high-voltage fuse does not need any changes, regardless of the plug-in or bus-type wiring can be directly connected. The micro switch end can be installed within the maximum range of 500mm from the fuse according to the power supply voltage of the high-voltage fuse. In addition, two M5 mounting screw holes are required on the bottom plate or other installation positions.

According to user needs, provide other wiring forms
