Frequently Asked Questions

Q1 What is the rated voltage of the HXGN17-12 Box-Type Fixed Metal Enclosed Switchgear?

The rated voltage of the HXGN17-12 switchgear is 12 kV, making it suitable for medium-voltage distribution systems in industrial and utility applications.

Q2 What is the difference between the FN12-12 and FZN25-12 configurations?

The main differences lie in their performance capacities. The FZN25-12 offers a higher breaking no-load transformer capacity (1600 kV/A vs. 1250 kV/A), a higher rated transfer current (2000 A vs. 1200 A), and a significantly longer mechanical life (10,000 times vs. 2,000 times) compared to the FN12-12.

Q3 What is the protection level (IP rating) of this switchgear?

The switchgear carries a protection level of IP2X, which provides protection against solid objects larger than 12.5 mm (such as fingers), ensuring safe operation in standard indoor environments.

Q4 What operating voltages are supported by the operating mechanism?

The operating mechanism supports both AC and DC voltages of 220V and 110V, providing flexibility for integration into various control and power supply systems.

Q5 What is the rated short-circuit breaking current of the combined apparatus?

The combined apparatus has a rated short-circuit breaking current of 31.5 kA, ensuring reliable fault interruption capability under high short-circuit conditions.

Q6 What are the standard dimensions of the HXGN17-12 switchgear cabinet?

The standard cabinet dimensions are 600(700) × 900 × 2000(1800) mm (Width × Depth × Height), with optional sizes available in parentheses to accommodate different installation space requirements.
