    Frequently Asked Questions
    QWhat is the difference between HGLC and HGLZ type disconnectors?
    The HGLC is a C-side operation disconnector designed for standard side-access switching, while the HGLZ is a transfer disconnector suited for applications requiring a switchable neutral pole and transfer between supply sources. The model suffix (C or Z) in the type designation indicates which variant is being specified.
    QWhat current ratings are available for the HGL series disconnector?
    The HGL series covers a wide range of rated currents: 63A, 100A, 160A, 250A, 400A, 630A, 1000A, 1250A, 1600A, 2000A, 2500A, and 3150A, making it suitable for both light commercial and heavy industrial power distribution applications.
    QWhat is the rated insulation voltage and impulse withstand voltage of the HGL disconnector?
    For 63A and 100A models, the rated insulation voltage (Ui) is 750V with an impulse withstand voltage (Uimp) of 6kV. For 160A models, Ui is 800V and Uimp is 8kV. For 250A and above, Ui reaches 1000V and Uimp is 12kV, ensuring compatibility with high-voltage distribution environments.
    QCan the HGL disconnector be operated externally or remotely?
    Yes. The HGL series supports both internal and external operation configurations. When external operation is required, it is specified in the type designation (position 5). Rear operation is also available as an option, indicated at position 1 of the type code. This flexibility allows integration into various panel and switchgear layouts.
    QWhat auxiliary contact configurations are supported?
    The HGL disconnector supports two auxiliary contact configurations: 1NO+1NC (code: 11) and 2NO+2NC (code: 22). The auxiliary contact function code is specified at position 3 of the type designation and can be omitted if auxiliary contacts are not required for the application.
    QHow do I select the correct HGL disconnector model for my application?
    Model selection is based on the required rated current, number of poles (3-pole or 4-pole with switchable neutral), operation mode (internal or external), wiring direction (front or rear), and auxiliary contact requirements. For example, a 630A 4-pole externally operated transfer disconnector would be specified as: HGLZ-630A/4J. Refer to the type designation table for a complete breakdown of each code position.
