Delixi CDW6i-ITR326 frame air circuit breaker ACB

Delixi CDW6i-ITR326 is a frame-type air circuit breaker (ACB) from Delixi. ITR326 is an intelligent release model, including specific types such as ITR326A (standard type) and ITR326H (advanced type). The relevant information is as follows:

Rated parameters: The rated current range is 400A to 6300A, and there are 1600AF, 2000AF, 2500AF, 3200AF, 4000AF, 6300AF and other frame grades to choose from. The rated voltage AC is 220V to 1140V with multiple options, suitable for AC 50Hz/60Hz circuits, and the number of poles is 3 poles and 4 poles.

Performance characteristics: Using DSP 32-bit high-speed processing chip, the data processing speed is fast. The innovative multi-layer metal mesh design of the arc extinguishing chamber 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.

Protection function: It has overload (L), short delay (S), instantaneous (I) and ground fault (G) protection functions, which can protect the line and power equipment from overload, undervoltage, short circuit, single-phase grounding and other faults. ITR326H also has advanced protection functions.

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 to distribute electric energy in the distribution network and protect lines and power equipment. 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 extreme temperature environments 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.
