Product Introduction
The DELIXI CDM6i-400L/3300 molded case circuit breaker is designed for power distribution network protection, suitable for 50Hz AC systems with rated operational voltage up to 400V. Featuring thermomagnetic trip technology, it provides both overload and short-circuit protection with 250A rated current and 400A frame size. The 50kA breaking capacity ensures reliable protection for electrical circuits and equipment. Its compact modular design simplifies installation in industrial control systems, motor protection circuits, and residential power distribution applications. 27
Key Features
This product utilizes precision thermomagnetic trip unit with adjustable settings for customized protection. The magnetic trip mechanism ensures fast response to short-circuit faults while thermal element handles overload conditions. Transparent cover allows visual status inspection, and direct handle operation enables manual control. With vertical/horizontal mounting flexibility and rear terminal connections, it optimizes space utilization in panel boards. Advanced arc quenching technology minimizes damage during fault interruption. 311
Technical Specifications
Rated insulation voltage: 400V; Rated operational current: 250A (adjustable 100A-400A); Poles: 3P without neutral. Dimensions: 75×120×60mm; Weight: approx. 1.2kg; Ambient temperature range: -5℃ to +40℃. Standard configuration excludes accessories, with optional shunt release and auxiliary contacts available. Thermal trip follows Class I curve, magnetic trip setting at 10-12×In for effective discrimination between startup currents and fault currents. 914
Application Scenarios
Ideal for main circuit and branch protection in power distribution systems to prevent equipment damage from overload/short-circuit. Widely used in industrial automation for motor and transformer protection, building power distribution for floor panels and busways, as well as specialized environments like renewable energy systems and rail transit. Selective coordination capability enables cascade protection with downstream breakers to enhance power supply continuity. 1013
