HH15/QSA Fuse-switch Disconnector
1.1 Application
Mainly used in the distributing and motor circu which has high short-circuit current, andacted 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.
1.2 Standard: IEC/EN 60947-3.
1.3 General characteristic
Full-enclosed structure
Unique rolling insert type contact system.
NHR17 Fuse-Switch Disconnector
1.1 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.
1.2 Standard: IEC/EN 60947-3.
NHR40 Fuse-switch Disconnector
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,
