    Installation and Usage Instructions
    • 1
      The switch should be installed vertically. The upper terminals should be connected to the power supply, and the lower terminals are for the load output. Pushing the handle upwards connects the circuit (ON) and shows a red indicator; pulling it downwards disconnects the circuit (OFF) and shows a green indicator.
    • 2
      Before applying power, operate the switch manually several times. The mechanism action should be flexible, reliable, and without any blockage.
    • 3
      The switch is allowed to infrequently make and break load currents (including appropriate overloads) when necessary. However, it must not be used to interrupt short-circuit currents.
    Frequently Asked Questions (FAQ)
    Q1: What is the primary function of the HL30 isolating switch?
    A1: The HL30 is an isolating switch (disconnector) designed exclusively for connecting and disconnecting power circuits. It serves to isolate the power supply for safety during maintenance but does not feature overcurrent, overload, or short-circuit protection.
    Q2: Can the HL30 disconnector be used to interrupt short-circuit currents?
    A2: No. The HL30 switch is not designed to interrupt short-circuit currents. It should only be used to make and break load currents under normal operational conditions or moderate overloads infrequently.
    Q3: How do the red and green indicators on the handle work?
    A3: The switch features a clear visual indicator: pushing the handle upwards connects the circuit (ON status) and displays a red indicator, while pulling the handle downwards disconnects the circuit (OFF status) and displays a green indicator.
    Q4: What are the installation requirements for the HL30 switch?
    A4: The switch must be installed vertically on a standard TH35-7.5 steel mounting rail. The upper terminals must connect to the incoming power supply, and the lower terminals connect to the outgoing load. The vertical inclination of the mounting surface should not exceed 5°.
    Q5: What are the ambient temperature and humidity limitations for operation?
    A5: The switch operates optimally in ambient temperatures between +5℃ and +40℃ (with a 24-hour average not exceeding +35℃). The relative humidity should not exceed 50% at +40℃, and the average relative humidity of the wettest month must not exceed 90%.
    Q6: What is the rated mechanical and electrical durability of the HL30?
    A6: The HL30 isolating switch is designed for high reliability, offering a mechanical durability of up to 8,500 operating cycles and an electrical durability of up to 1,500 operating cycles.
