Wedge Type Contact Fuse, J Type Fuse, Lv Cut out Fuse

Wedge type contact fuse, used in AC power grids, should only be accessed and replaced by suitable professionals. The rated voltage of the fuse link is AC 400 V, and the rated current is up to 630 A. The standard does not include requirements for fuses used in DC power grids and fuses with indicator devices.

Note 1: This fuse link is intended for future use in standard voltage AC 400V systems. Due to the fact that many countries still use open circuit voltage AC 433 V during the transition period, A distribution transformer with a load voltage of AC 415 V, therefore this fuse link will continue to be powered by AC 415 V and tested until the power supply drops to a lower level Voltage value. The fuse link should be tested with a minimum recovery voltage of AC 457 V (i.e. AC 415 V+10%).

Note 2: This fuse link is very similar to the standard "gG" type fuse link. In order to ensure good selectivity with the high-voltage fuse link on the primary side of the transformer, The action performance of this fuse link is fast (especially in the short term). The performance of this fuse link is expected to be consistent with the requirements of gG. During the transition period, this fuse.

The range and usage category of system I are defined as gU.
