NHR17 Fuse-switch Disconnector
▪ NHR17 series fuse-swith disconnector is a new product developed by our company. ▪ Rated insulation voltage up to 800V, rated operational voltage up to 690V. ▪ Rated operational current up to 630A, rated frequency 50Hz, in the distribution circuit and motor circuit which has high short-circuit current as the power switch, isolating switch, emergency switch as well as circuit protection, but normally it is not used to make and break a single motor directly.
NHR17
▪ Standard: IEC/EN 60947-3. ▪ Rated current: 160~630A.
NHR40 Fuse-switch Disconnector
▪ 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 or switch off on load and provide safely isolation and protection against overcurrent for any voltage electrical circuit.
