The GYW6 series intelligent universal circuit breaker (hereinafter referred to as the circuit breaker) is suitable for distribution networks with AC 50Hz, rated voltage up to AC690V and below, and rated current ranging from 200A to 6300A. It is used to distribute electrical energy and protect lines and power equipment from the hazards of under voltage, short circuit, single-phase grounding, and other faults. The circuit breaker has intelligent protection function and precise selective protection, which can improve power supply reliability and avoid unnecessary power outages. At the same time, it has an open communication interface and can be used for "four remotes" to meet the requirements of the control center and automation system. The circuit breaker has a pulse withstand voltage of 8000V at an altitude of 2000 meters (corrected according to standards for different altitudes, with a maximum voltage not exceeding 12000V). This circuit breaker does not come with an intelligent controller or sensor and can be used for isolation. The circuit breaker complies with the standards GB/T14048.2 and IEC60947-2 "Low voltage switchgear and control equipment - Part 2: Circuit breakers".
Intelligent controller performance:
a. Intelligent controllers are divided into: 2M type (ordinary intelligent type), 2H type (communication type), 3M (liquid crystal type), and 3H
(liquid crystal communication type)
b. Equipped with overload long delay inverse time limit, short delay inverse time limit, timing limit, and instantaneous functions. The required
protection characteristics can be set by the user;
c. Single phase grounding protection function;
d. Display function: current display, voltage display (note instructions when ordering);
e. Alarm function: overload alarm;
f. Self inspection function: overheating self inspection, microcomputer self diagnosis;
g. Test function: Test the action characteristics of the controller.
