Arc-proof Air-insulated Switchgear for Primary Distribution 12kV 630...2000A 25kA

Description：

LeanGear ZS9 is an arc-proof air-insulated switchgear designed to meet space requirements and ratings of low electrical distribution grids.

It offers optimal safety and reliability standards, consistent with the ABB’s UniGear range of switchgear. With a proven robustness and flexibility,  the LeanGear ZS9 is tested for tropical conditions.

Main benefits：

• Safety: Increased safety level assured by integrated ducting system against effects of internal arc.
• Security: Comprehensive interlocks provide optimum protection for both personnel and equipment.
• Space: Maximum functionality in a compact design with reduced footprint and height.
• Service: Ease of service and operation by personnel as switchgear and cable termination height are ergonomically designed.
• Speed: Minimal service downtime attributable to modular circuit breaker design and built-in features that eliminate use of special handling tools.
•  Strength: Robust panel structure that is proven against external mechanical impacts.
