HA3-6300 Intelligent universal circuit breakerDetailed product description：

HA3-6300 intelligent universal circuit breaker, with a rated current of 630A~6300A, is suitable for AC 50Hz, 400V, 690V. It is mainly used in low-voltage distribution networks to distribute electrical energy and protect lines, prevent power equipment from being damaged by overload, short circuit, undervoltage, one-way grounding and other faults. Equipped with a high-precision intelligent controller, it can achieve full selective protection of overcurrent and residual current in the distribution system. At the same time, it has communication function and can be used as the main component of the "four remote" functions of remote control, remote communication, telemetry, and remote adjustment in control systems such as fieldbus.

The HA3-6300 intelligent universal circuit breaker has high breaking capacity and no arcing. It has multiple operation, installation, wiring methods, mechanical interlocking between products and cabinet doors, as well as functions such as display of operating parameters, fault memory, on-site setting, testing, thermal memory, load monitoring, and self diagnosis, which can ensure the quality and reliability of system power supply. It is the largest capacity circuit breaker in China and even in the world.

5. Technical features
The product structure features modular functional components, small size, beautiful appearance, high dynamic and thermal stability, high breaking capacity (120KA), no arcing, integrated detection, three-stage protection, monitoring, display, alarm, communication, self diagnosis, on-site setting, testing functions, etc. And it has the following innovative characteristics:
(1) Adopting a novel design, the electric repulsion during short circuit is reduced, the contact area is increased, and the breaking capacity and dynamic thermal stability are improved;
(2) The spindle is segmented and equipped with multiple semi-circular bearings to overcome spindle deformation;
(3) Measures such as adding shielding to transformers, adding auxiliary coils, and fine-tuning phase have been taken to improve the accuracy of current acquisition;
(4) We have developed a new type of contact material, AgNi30C3, Ensure end-to-end capability and wear resistance;
(5) The use of dragging devices at both ends of the shaft solves the problem of balancing drawer rocking in and out.
HAI-6300 intelligent universal circuit breaker is the largest capacity circuit breaker in China and even in the world. This product has four remote functions including remote adjustment, telemetry, and remote control. Its performance indicators are comparable to international advanced products such as Schneider M series from France and 3WN6 series from Siemens from Germany.
