Product Description :
DNTRS strip type fuse railwith unique process engineering.
1. Integrating of current transformer and fuse switch initiated
domestically.
2. With knife-edge entry and arc extinguishing equipment, it is
safe for operation.
3. The isolating knife blade, full-range protection and
semiconductor protection fusible core are optional.
4. Fuse wire monitor and signal switch can be additionally mounted;
with self-closing fuse wire monitoring hole.
5. It can be used as primary switch, instaneous breaking capacity
reaches 100kA.
6. Capacity of operating with load reaches 1.3 times of rated
current
7.Busbar mounting in 100MM or 185MM
Scope of application
1 . DNTRS bar fuse holder used in AC 50(60) HZ 100mm 0r 185mm busbar system with rated voltage up to 690V and rated current to 630A, it is mainly used for overload and short circuit protection circuit.
2 . DNTRS bar fuse holder has been widely used for box tansformer and cable branch box.
3 . DNTRS bar fuse hold complies with standard of GB13539.2,iEC60269.2 and IEC60947.3.
Structure feature
1 . DNTRS series bar fuse holder is mainly mounted in rail of bus,which intergates three single-pole fuse holders in end-to-end arrangenment,A contact(feeding contact) of each phase is connected with one phase of bus,and other contacts(output contact)are equipped with conductorconnection unit.
2 . The DNTRS bar fuse holder carring live part is made of fibre reinforced plastic(FRP),Ag-plated fuse contact with Tin-plated end block ensures low power loss,high acceping power and work temperature.
3 . DNTRS bar fuse holder can be fixed by screw or hook.When it is mounted with hook,the busbar does not need punching, which makes the installation easier,more flexible and more reliable.
