Product Description

The DLX-CDB-12-250V is a compact DLX-CDB-12 circuit breaker designed for 250V DC applications, part of the DLX series protection devices. This 250V DC MCB features 1 input and 1 output channel, supporting direct connection to up to 4 auxiliary modules. Equipped with a RS485 communication interface, it integrates seamlessly into industrial control systems. Operating within 24-250V DC and a temperature range of -25°C to +60°C, it ensures reliable performance in harsh environments such as renewable energy systems, telecom infrastructure, and railway power distribution. Key advantages include rapid fault isolation, modular expandability, and a durable design with IP65 protection. The device incorporates a 2.4-inch status display for real-time monitoring, though its fixed current rating limits customization. Its arc-quenching technology ensures a short detection response time of <10ms, enhancing safety in high-voltage DC circuits.
