Important Notes

• This listing is for the GPS8-17 series.
• Confirm whether you require the 110V or 220V version.
• Confirm the rated current: 63A or 80A.
• The 63A and 80A versions may have different specifications.
• The 80–400V operating range does not mean every voltage is suitable for every configuration.
• Overcurrent protection settings do not replace correctly rated short-circuit protection unless specifically confirmed by the manufacturer.
• Check the wiring diagram, switching specifications, and electrical compatibility before installation.
• Professional installation by a qualified electrician is recommended.
