Chint universal circuit breaker NA1-2000X-1250A

The Chint universal circuit breaker NA1-2000X-1250A is an electrical device suitable for power distribution networks with an alternating current (AC) frequency of 50Hz, a rated working voltage up to AC690V, and a rated working current up to 6300A and below. The following detailed introduction will be presented from dimensions such as its functional characteristics, application scenarios, and technical parameters:  

 Functional Characteristics  

- **Comprehensive Protection Functions*CHNT NL1E - 63A circuit breaker 

  It provides multiple fault protections for circuits and power equipment, including overload, undervoltage, short circuit, and single-phase grounding. When an overload occurs in the circuit, the thermal element of the thermal release generates heat, causing the bimetallic strip to bend, which pushes the free release mechanism to act and disconnect the main circuit. In case of a short circuit or severe overload, the armature of the overcurrent release is attracted, also causing the free release mechanism to act and cut off the circuit.  

- **Intelligent Control*Chint NXBLE-40C6 residual current circuit breaker (RCCB)*

  Equipped with intelligent protection functions, it offers precise selective protection. It can real-time monitor parameters such as current, voltage, and power, and perform intelligent control and protection according to set rules, improving power supply reliability and avoiding unnecessary power outages.  

- **Diverse Operation Modes*Chint NXR series thermal overload relays price* 

  The operating mechanism can be installed on the front or right side, supporting both manual operation and electric closing, facilitating users to operate in different scenarios. Meanwhile, it is equipped with "trip" and "close" indicators as well as a manual disconnection button, enabling operators to intuitively understand the working status of the circuit breaker.  

- **Abundant Accessory Expansion*CHINT circuit breaker price* 

  With complete accessory expansion functions, it can meet the needs of extended functions in different application scenarios. For example, adding auxiliary contacts, alarm contacts, shunt trip devices, undervoltage trip devices, etc., to achieve more control and monitoring functions for the circuit.
