Application

      HR3 series fuse-switch-disconnector is suitable in the distributing system of AC 50Hz, 380V, rated current up to 1000A and acted as protection to short-circuit and over-load of the cable and conductor. In normal condition, it can infrequently make and break the normal loaded current and over-load current with hand, the current will be cut off by the fuse under short-circuit condition.

This product is in conformity with standard GB14048.3(idt IEC60947-3).

    

Normal work conditions and Installation conditions

  • Ambient temperature: -5°C~40°C.

  • Altitude: shall not exceed 2000m.

  •  The atmosphere condition: The relative humidity shall not exceed 50% when the environmental temperature is +40°C in installing place; And the relative humidity may be higher at the lower temperature condition. Such as when the humidity is 90% when the temperature is +20°C .It shall take some special management to avoid the dew occurs on the product surface due to temperature change.

  •  Pollution grade: UJ

  •  The product shall be installed in the place without remarkable shake, strike and quiver, rain and snow, in the medium without danger of exploding, and in the places without gas and conductive dust, which can make the metal go rust and affect insulation performances.

Structure characteristic

        Fuse-switch-disconnector (hereinafter referred to switch) is a combined appliance composed of fuse and knife switch, it has the basic property of fuse and knife switch,when the circuit is normally supplied, the knife switch will make and break the power supply.

        The fuse wire in the fuse may be melted and cut off the error current promptly when the circuit or the electric consumer is overloaded or short-circuit. For the front operated, front overhauled switch, there is a door in the center of the switch for overhaul and replacement of fuse, it is mainly installed on BDL distributing panel. The front operated, rear overhauled switch is mainly installed on BSL distributing panel. The side operated, front overhauled switch can be developed into enclosed power distributing box.
        The fuse of the switch is fixed on the insulated cross beam what has spring and lock plate, it ensures the fuse will not trip under normal running state; Press down the lock plate to replace the fuse when the fuse is melted because of circuit fault.
