Frequently Asked Questions (FAQ)
Can this switchgear be used in high-altitude environments?
Yes. While the standard design is rated for altitudes ≤1000m, special customizations are available. Currently, there are 6 sets operating reliably at an altitude of 5200m. Please specify your requirements when placing an order.
What standards does this switchgear comply with?
The switchgear complies with major national and international standards, including GB3906-2006, IEC 60298-1990, and GB/T11022-2011.
What is the IP protection level of this equipment?
This switchgear features an IP3X level of protection, which ensures sufficient safety against external solid objects.
What are the temperature and humidity limits for normal operation?
It operates within an ambient temperature range of -35℃ to 45℃ (daily average difference ≤25℃). The daily relative humidity should not exceed 95%, and the monthly average relative humidity should not exceed 90%.
How do I choose the correct height dimension for my cabling?
