Qiaonasen introduces a new generation of withdrawable circuit breakers for the harsh conditions of Russia 

Qiaonasen Electric officially introduces a new series of draw-out type air circuit breakers (ACB) to the markets of Russia and the CIS countries. The equipment is designed to withstand low temperatures and difficult industrial conditions, providing a reliable and flexible solution for power supply to energy facilities, heavy industry and infrastructure.

Key Benefits

• Operational service: Precision guide design maintains three distinct positions: Connected, Test, Disconnected. The breaker module can be replaced without disconnecting the power cables, reducing MTTR to a minimum and ensuring continuity of production processes.
• Frost resistance and durability: Components have been specially treated to operate at low temperatures, and optimized ventilation channels ensure stable operation in extreme ranges from -25°C to +70°C.
• Intelligent protection: The standard equipment includes a high-precision electronic trip unit with 4-stage protection (overload, short circuit, selective, ground fault) and support for remote monitoring for integration into automated process control systems (SCADA).

Full compliance and flexible configuration

• Certification: The entire line has certificates EAC and GOST-R, as well as a full package of technical documentation in Russian, which guarantees trouble-free acceptance.
• Wide range of models: Available in rated currents from 630A to 6300A in 3P and 4P configurations, fully adapted to local grounding systems (TN-S, TN-C-S).

Areas of application

Qiaonasen withdrawable circuit breakers are already successfully used in power plants, metallurgy, mining and large logistics centers. Qiaonasen Electric continues to provide cost-effective end-to-end solutions to modernize energy infrastructure in the Eurasian region.
