GW1 630A to 6300A Air Circuit Breakers ACBPDF
The GW1 Series intelligent universal air circuit breakers are a specific type of air circuit breakers designed for use in electrical distribution networks. Here are some key features and characteristics of the GW1 Series:
2.2.1 installation
A.-fixed
B.-drawer
2.2.2 number of poles: three-pole and four-pole
2.2.3-by mode of operation
A. Electrical operated
B. manual operation (repair and maintenance)
2.3 tripping device type
Intelligent controller, under the instantaneous voltage (or delayed) release, and shunt release.
2.4 performance intelligent controller
A. intelligent controller are: h-type (communications), m (General Intelligence), l-(budget);
B. overload for long-time inverse-time overcurrent, short delay inverse time, definite and instantaneous functions.
Composition can be set by users themselves need protection;
C. single phase grounding fault protection features;
D. display: the display, operation current display setting current, line voltage display (voltage display should be made
at time of order);
E. alarm: overload alarm.
F. self-inspection function: hot post, computer diagnosis;
G. test function: test controller operation characteristics.
