Product Description

The VB40.5-CKM Circuit Breaker, a core component of the VB Series 40.5kV lineup, is engineered for high-voltage applications within the CKM19/S90 Switchgear system. It features 8 programmable inputs and 6 relay outputs, enabling direct integration with up to 4 auxiliary modules for enhanced control flexibility. Supporting RS485, Modbus, and Ethernet interfaces, this breaker operates reliably across a voltage range of 35-40.5kV and withstands temperatures from -25°C to +55°C, ideal for power distribution networks, industrial plants, and renewable energy substations. Key advantages include its modular design, arc-resistant construction, and a rapid fault-detection system with a 10-meter sensing range. A compact 5.7-inch HMI screen provides real-time diagnostics, while its integrated 200Ah backup battery ensures continuous operation during grid instability. Though optimized for durability, its advanced features may require specialized maintenance expertise.
