Product Overview
DELIXI CDW6i-4000N 2500A frame circuit breaker is an intelligent power distribution protection device designed for 50Hz AC networks with rated operational voltage of 380V. Featuring a three-dimensional layout, its optimized contact system and arc-extinguishing chamber ensure reliable breaking capacity under both normal and fault conditions. The withdrawable design facilitates maintenance while mechanical closing lock and multi-status indicators enhance operational safety. With IP40 protection class, it operates stably in environments from -40℃ to 70℃.28
Key Features
This breaker provides comprehensive protection including long-delay overcurrent, instantaneous short-circuit and undervoltage protection (230V coil). Precision current monitoring is achieved through electronic trip unit with backlit LCD displaying real-time parameters. Unique spring-energy storage mechanism supports both manual/electric operations, with clear mechanical energy status indication. Low-contact-resistance main circuit uses high-conductivity materials, and the knife-contact design ensures electrical stability during racking operations.310
Technical Specifications
With 4000N frame size and 2500A rated current, it offers rated insulation voltage of 1000V. The three-phase four-wire withdrawable version has three positions (connected/test/disconnected) and mechanical endurance exceeding 10,000 cycles. Arc-extinguishing system combines metal grids and gas ionization technology, achieving 65kA breaking capacity (400V AC). Standard configuration includes 6 auxiliary contacts (4NO+2NC), expandable to 12 pairs. Undervoltage release operates reliably within 70%-110% rated voltage while shunt trip responds within 30ms.58
Applications
Ideal for main circuit protection in smart buildings, industrial plants and mining power stations. Effectively safeguards distribution lines and equipment against short-circuit, overload and grounding faults. In 380V AC networks, serves as main incoming switch or large-capacity motor protector. Modular design allows communication module integration for remote monitoring when required.414
