    ❓ Frequently Asked Questions
    Q
    What is the rated voltage of the GN30-12 series disconnector?
    A
    The GN30-12 series disconnector has a rated voltage of 12 KV, making it suitable for medium-voltage switchgear applications.
    Q
    What rated current options are available for the GN30-12 series?
    A
    The GN30-12 series is available in four rated current options: 400A, 630A, 1000A, and 1250A, covering a wide range of load requirements.
    Q
    What is the difference between the GN30-12M and GN30-12DM models?
    A
    The GN30-12M and GN30-12DM share the same electrical specifications. The "DM" designation typically indicates a double-pole or specific mounting/drive configuration. Please refer to the product model diagram for detailed structural differences.
    Q
    What is the rated short-time withstand current for the 1000A and 1250A versions?
    A
    Both the 1000A and 1250A versions share a rated short-time withstand current of 31.5 KA, with a corresponding rated peak withstand current of 80 KA and a short-circuit duration of 4 seconds.
    Q
    What are the insulation withstand voltage levels for the GN30-12 series?
    A
    The lightning impulse withstand voltage is 75 KV phase-to-phase/to earth and 85 KV across open contacts. The 1-minute power frequency withstand voltage is 42 KV phase-to-phase/to earth and 48 KV across open contacts.
    Q
    Where can I find the dimensional drawings for the GN30-12 disconnector?
    A
    The dimensional drawings for the GN30-12 series are provided in the "Dimension" section above. The diagrams illustrate the installation dimensions and structural layout for accurate engineering and installation planning.
