Product Description

Product Description

 Customizable 2000A Circuit Breaker Solutions  IP65 Protected 

    The SJKW1 series intelligent universal circuit breaker (hereinafter referred to as the circuit breaker) is designed for use in distribution networks with an AC frequency of 50 Hz, a rated voltage up to 660 V (or 690 V), and a rated current ranging from 200 A to 6300 A. It is capable of distributing electrical energy while providing protection against faults such as overload, undervoltage, short circuit, and single-phase grounding. The circuit breaker features intelligent protection functions and precise selective protection capabilities, which enhance the reliability of power supply and prevent unnecessary power outages. Additionally, it is equipped with an open communication interface that supports "four remote" operations, thereby meeting the requirements of control centers and automation systems. The circuit breaker is suitable for installation at altitudes up to 2000 meters, with a pulse withstand voltage of 8000 V (adjusted according to the relevant standards for different altitudes, with the maximum value not exceeding 12000 V). In configurations without an intelligent controller or sensor, the circuit breaker can function as an isolator. 
    This product complies with international and national standards, including GB14048.2 "Low-voltage Switchgear and Controlgear - Low-Voltage Circuit Breakers" and IEC60947-2 "Low-Voltage Switchgear and Controlgear - Circuit Breakers."

General

    

    The universal frame circuit breaker 2000 series is a high-current protection device used in low-voltage distribution systems, with a rated current typically ranging from 1600A to 2000A. It is suitable for use as main switches or critical branch protection in power distribution systems. This circuit breaker is available in two mounting configurations: withdrawable type and fixed type, and comes in both 3-pole (3P) and 4-pole (4P) specifications.

  The withdrawable design facilitates maintenance and replacement, featuring three operational positions: "Connected/Test/Isolated" for safe operation without power interruption. The fixed-type structure is simple, directly installed in distribution cabinets at lower cost, though maintenance requires power shutdown for disassembly.

   3P circuit breakers are suitable for three-phase three-wire systems (such as motor-driven power loads), while 4P circuit breakers are designed for three-phase four-wire systems (including neutral line, applicable for mixed power and lighting loads), providing more comprehensive protection.

   Featuring high breaking capacity (typically above 65kA), these circuit breakers support intelligent trip units for overload, short-circuit, and ground fault protection. They can be equipped with motorized operating mechanisms and communication modules (such as Modbus), making them ideal for industrial, commercial building, and data center applications.

FAQ

Q: What are the typical applications for your air circuit breakers?

How do I select the right size (current rating) ACB for my application?

 How do I ensure the ACB has sufficient breaking capacity (Icu/Ics) for my system?

A: Our ACBs are widely used as main incoming feeders, couplers, and large outgoing feeders in:

Industrial power distribution systems (factories, plants)
Commercial buildings (data centers, hospitals, shopping malls, hotels)
Infrastructure projects (ports, airports, power stations, substations)
Marine and offshore installations (if applicable, mention specific certifications)
Renewable energy systems (solar farms, wind farms).

A: Selecting the correct current rating involves:

Calculating the total maximum continuous load current of the circuit.
Applying relevant derating factors (ambient temperature, enclosure, grouping).
Choosing an ACB with a Rated Current (In) equal to or higher than the calculated value. We strongly recommend consulting with our technical team to ensure optimal selection based on your specific load profile and system requirements.

A: The ACB's Ultimate Breaking Capacity (Icu) must be equal to or greater than the prospective short-circuit current at its installation point in your electrical network. This requires a short-circuit study of your system. We can provide guidance based on typical system levels or review your specific data.
