1.1 NHR40 series switch-disconnector with fuse
is applicable in the circuit of AC50Hz,
rated voltage AC690V and below,
DC440V and below,
rated current up to 630A.
NHR40 series are infrequently manually operated
multipolar fuse combination switches,
They break of switch off on load
and provide safely isolation
and protection against overcurrent
for any voltage electrical circuit.
