HH15-QA/QP Switch Disconnector
NHR17 Fuse-switch Disconnector
• Mainly used in the distributing and motor circuit which has high short-circuit current, and acted as main switch or master switch infrequently operated by hand, it is particularly suitable in the relative high class with drawable low voltage complete equipment. • They provide safety isolation and protection against overcurrent for any low voltage electrical circuit.
• 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.
• Standard: IEC/EN 60947-3 • Rated current: 125~3150A
• Standard: IEC/EN 60947-3. • Rated current: 160~630A.
