  • Scope of Application

    NHL30 Electrical Isolation Switch (NHL30 electrical isolator switch) is used for AC 50Hz or 60Hz, the power distribution and control circuit of rated voltage 230V or 400V and below, the current to the top of the power distribution device and 100A between the No load division. Mainly as the total switch of electrical terminal appliances, electrical isolator switch can also be used to control all types of motors, low-power electrical appliances, lighting and other places. Mechanical and electrical life have 10,000 times, of which electrical life has 6000 times.
    NHL30 electrical isolator switch meets GB14048.3 and IEC947-3 and other standards.

    Model and meaning

    Use environment and working conditions

    ◆ ambient air temperature -5 degrees Celsius to +40 degrees Celsius, the average temperature does not exceed +35 degrees Celsius.
    ◆ altitude of not more than 2000m.
    ◆ the relative humidity of the atmosphere +40 measures not more than 50%, the wettest month is 90%.
    ◆ pollution level II.
    ◆ Use category AC-22A.
    ◆ installation form using TH35-7.5 steel installation rail installation, other surface and the vertical inclination of the body is not directly over five degrees.

    Structural features

    NHL30 electrical isolator switch switch contact system adopts double break direct acting structure, high current selects two parallel and contact group, both to increase the current capacity and also make full use of electric power compensation. At the same time, the spring of handle operating mechanism store energy to break-make rapidly. To overcome the impact of slow manpower operation and greatly improve the possibility of the work, there are striking identification show the contact on and off to prevent misuse and improve security.

    Installation and usage

    ■ Before installing HL30 electrical isolator switch, check whether the switch is in accordance with the actual operating conditions.
    ■ Installing into the installation rail according to the graphical position, the handle push-up means making, indication sign is red; handle pull-down means breaking, indication sign is green.
    ■ The power supply line is accessed from the top of the switch and connect the outlet from the bottom, copper wire should be tightened, should not be loose , or copper wire is exposed outside the terminal.
    ■ Before power-on, there are switches manually operate several times in advance, it should be flexible and reliable and has no blocking phenomenon.
    ■ HL30 electrical isolator switch should not be affected by rain in the use, storage, transportation and other processes.
    ■ HL30 electrical isolator switch can carry (short-circuit) current under abnormal circuit condition for a certain period of time, or it can be appropriate overload of less frequent making-breaking , but it can not be used for breaking fault current.
