Frequently Asked Questions

What is the primary function of the HGL isolating switch?

The HGL isolating switch is mainly used for power distribution circuits and motor circuits where frequent connection and disconnection is not required, serving as a reliable electrical isolation point during maintenance or circuit inspections.

What current ratings are covered in the HGL series?

The series offers a wide operational current range from 16A up to 3150A, designed to support both low-current and heavy industrial high-power electrical applications.

Does this isolating switch support operation outside the cabinet?

Yes, with the optional "J" derivative code design, the isolating switch is equipped for operation outside of the electrical cabinet. Standard designs operate from within the cabinet.

What certifications and safety standards do HGL switches comply with?

HGL isolating switches comply with standard international electrical specification IEC 60947-3, Chinese national standard GB/T 14048.3, and are CCC certified.

Can auxiliary contacts be configured with the switch?

Yes, they support configuration options for auxiliary contacts. You can select either a single pair of assistants (code 11) or two pairs of supports (code 22) based on control system integration needs.

Is the handle customizable for higher current models like HGL-2000~3150A?

Yes. While the A-type handle is standard with a total length of 405mm, the shorter B-type handle (330mm length) can be customized separately according to physical spatial constraints of your distribution boards.
