Introduction

 

The low-voltage circuit breakers (hereinafter referred to as circuit breakers) are suitable for the distribution network of AC 50Hz, rated voltage up to 660V (690V) and below, and rated current 400A~6300A, used to distribute electrical energy and protect circuits and Power supply equipment is protected from faults such as overload, undervoltage, short circuit, single-phase grounding, etc. The circuit breaker has an intelligent protection function and precise selective protection, which can improve the reliability of power supply and avoid unnecessary power outages. At the same time with an open communication interface, it can carry out four remote control to meet the requirements of control center and automation system. The circuit breaker has an impulse withstand voltage of 8000V at an altitude of 2000 meters (different altitudes are corrected according to the standard, and the maximum is not more than 12000V) The circuit breaker can be used as an isolator without an intelligent controller and sensor, marked as one.
The circuit breaker meets the standards of GB14048.2 "Low-voltage switchgear and control equipment low-voltage circuit breaker" and IEC60947-2 "Low-voltage switchgear and control equipment circuit breaker"

 

Feature

 

  1. has 3 poles and 4 poles, drawer type and fixed type, can be installed into the line;
  2. has a variety of intelligent controllers, providing different functions: intelligent function, display function.
  3. setting function, monitoring function, fault memory function, can bring communication interface to achieve telemetry, remote adjustment, remote control, remote communication; O protection features are complete, setting is convenient, high precision, with instantaneous, short delay, long delay, single Protection features such as phase grounding.

 

classification


1 According to the installation method
a. Fixed b. Drawer
2 According to the number of poles: three poles, four poles
3According to operation mode
a. Electric operation
b. Manual operation (for inspection and maintenance) O release type
Intelligent controller, instantaneous (or delay) undervoltage release, shunt release.
Intelligent controller performance:
a. Intelligent controller is divided into: H type (communication type), M type (general intelligent type), L type (economic type); b. has overload long delay inverse time limit, short delay inverse time limit, timing limit, instantaneous Features. The required protection characteristics can be set by the user; C. Single-phase grounding protection function; d. Display function: setting current display, operating current display, voltage display of each line (voltage display should be proposed when ordering); e. alarm Function: overload alarm; f. self-check function: overheat self-check, microcomputer self-diagnosis; g. test function: test the action characteristics of the controller.

 

Normal working conditions and installation conditions


ambient air temperature
The upper limit value does not exceed +40°C, the lower limit value does not fall below -5°C, and the average value of 24h does not exceed +35°C; Note: The lower limit value is -10°C or -25°C working conditions, the user should report to the factory Affirmation: The working conditions of the upper limit value exceeding +40℃ or the lower limit value lower than -10℃ or -25℃, the user should consult with our factory.
The altitude of the installation site does not exceed 2000m.
◎Atmospheric conditions
The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is +40°C. It can have a higher relative degree at a lower temperature. The average maximum relative humidity of the wettest month is 90%, and the average minimum temperature of the month It is +25 ℃, and consider the condensation on the surface of the product due to temperature changes. Users who exceed the requirements should consult with our factory.
◎Protection grade: IP30
