Product Description

VSG-24 24KV Draw-out Type Vacuum Circuit Breaker

VSG-24 Series 24kV Withdrawable Vacuum Circuit Breaker is a high-performance indoor medium-voltage switchgear device designed for 3-phase AC 50/60Hz power systems with rated voltage up to 24kV.

The breaker adopts a withdrawable (truck-mounted) structure and is suitable for matching with metal-clad switchgear such as KYN28-24 type cabinets. It is widely used for protection and control of electrical equipment in power plants, substations, industrial and mining enterprises.

The product integrates advanced vacuum interruption technology and modular spring operating mechanism to ensure safe, reliable, and long service operation.
