Delixi CDW6i-4000NHM is a frame-type air circuit breaker (ACB), where "4000" represents the frame grade current of 4000A, and "N", "H" and "M" represent different breaking grades. The relevant introduction is as follows:
Rated parameters: The rated current range is 400A to 6300A. The rated voltage AC has a variety of options such as 220V, 230V, 240V, 380V, etc., up to 1140V (M type), suitable for AC 50Hz/60Hz circuits, with 3 poles and 4 poles.
Performance characteristics: Using DSP 32-bit high-speed processing chip, fast data processing speed. With innovative multi-layer metal mesh design of arc extinguishing chamber, it can achieve true zero arcing. Ics (operating short-circuit breaking capacity) is up to 135kA, and Icu (ultimate short-circuit breaking capacity) is up to 135kA, which can achieve full selective protection and ensure the continuity and stability of power supply.
Protection function: It has protection functions such as overload, undervoltage, short circuit, single-phase grounding, etc., which can protect lines and power equipment. It may also have an alarm non-tripping function to achieve precise protection.
Installation and wiring: There are two installation methods: fixed and drawer, and the wiring methods are horizontal rear connection and vertical rear connection.
Scope of application: It is mainly used for distributing electric energy in the distribution network. It can be widely used in power stations, factories, mines and modern high-rise buildings, especially the distribution system in intelligent buildings. It can be used in an ambient temperature of -40℃ to 70℃, and the altitude adaptation range can reach 5000m.
Supporting accessories: It can be equipped with locking and interlocking accessories such as button protection lock, mechanical door interlock and safety baffle lock, as well as remote operation accessories such as opening and closing coils, undervoltage coils, and circuit protection accessories such as N-phase external transformer and grounding transformer.
