Chint NHRT40 NHRT40-160/3 NHRT40-250/3 NHRT40-400/3 NHRT40-630/3 160A 250A 400A 630A CHNT Vertical Fuse Switch Disconnector
Chint NHRT40 Vertical Fuse-switch Disconnector
1 Application
NHRT40 series vertical fuse-switch disconnector is applicable in the circuit of rated voltage AC690V and below, rated current AC 160A-630A, rated frequency of 50Hz. NHRT40 series are infrequently manually operated multipolar fuse combination switches.
They break or switch off on load and provide safely isolation and protection against overcurrentfor any voltage electrical circuit.
2 Standard: IEC 60947-3.
3. Structure and features
3.1 Structure: The switch is consisted of underpan, base, cover, handle and shield.
3.2 NT series fuse link is installed in the cover to act as knife of active contact.
3.3 The handle moves fan-shapely based on the pivot of underpan, makes the cover and fuse make and break together,
it is with enough space and remarkable disconnection point which meets the requirement of disconnector switch.
3.4 It is convenient to dismount the base and underpan, which is easy to mount the base to the busbar safely and reliably.
3.5 There is arc extinguisher on the underpan, which ensures breaking capacity of the switch.
