    Frequently Asked Questions
    QWhat is the HR17 fuse-type isolating switch used for?
    The HR17 fuse-type isolating switch is designed for use in power distribution systems to provide both isolation and overcurrent protection. It is suitable for AC circuits up to 1000V and rated currents from 40A to 800A, commonly used in industrial control panels and distribution boards.
    QWhat are the available pole configurations for the HR17 series?
    The HR17 series is available in 2-pole (2P), 3-pole (3P), and 4-pole (4P) configurations, allowing it to be used in single-phase, three-phase, and four-wire electrical systems depending on the application requirements.
    QWhat is the difference between the fixed type (C) and plug-in type (T)?
    The fixed type (indicated by "C") is permanently mounted to the panel or enclosure, providing a stable and rigid installation. The plug-in type (indicated by "T") allows the switch unit to be inserted and removed from a base, facilitating easier maintenance and replacement without rewiring.
    QWhat does the auxiliary contact option mean in the HR17 model code?
    In the HR17 model designation, the digit "1" indicates that the switch is equipped with auxiliary contacts, which can be used for remote signaling or interlocking with other control devices. The digit "0" means no auxiliary contacts are included.
    QWhat is the rated short-circuit current capacity of the HR17 series?
    The HR17 series has a rated short-circuit current of 50kA, with a peak value of 105kA. This high short-circuit withstand capability ensures reliable performance and safety in demanding industrial power distribution environments.
    QWhich international standard does the HR17 fuse-type isolating switch comply with?
    The HR17 series is designed and tested in compliance with the IEC60947-3 standard, which covers switches, disconnectors, switch-disconnectors, and fuse-combination units for industrial use. This ensures the product meets internationally recognized safety and performance requirements.
