High-Performance Air Circuit Breaker 1600A–6300A, Fixed and Drawout Type

Product Quality

The moving and stationary contacts are made of copper, while the moving and stationary points are made of silver alloy, offering advantages such as high-temperature resistance, oxidation resistance, and excellent conductivity

		The incoming and outgoing copper busbars are made of thick standard-grade pure copper material

The drawer base adopts the standard thickness of copper busbar, and the clamp that interlocks the drawer base with the circuit breaker body is a copper clamp

		The controller adopts the technology of SunTech and Kefeng, and the circuit board undergoes a 24-hour aging test

The undervoltage release coil is sourced from Jiangsu Guoxing, with the coil winding count meeting the standard

Management quality

Material Inspection (Contact Spring Pressure, Detection of Contact Points and Copper Busbar Defects, Cold Soldering)

		Batch trial assembly qualification range (travel, clearance, contact pressure, tripping force)

Semifinished Product Inspection (Excess Distance Opening Circuit Resistance, Three-Phase Synchronous Closing Full Inspection, Mechanical Reset Operation 15 Times Full Inspection, Mechanism is Whether there is false closing, the above-mentioned other factories may not perform these tests (instantaneous, delayed, short-circuit debugging)

		Finished Product Inspection (5 operations of closing and opening, energy storage, undervoltage tripping, and power-on tests for incoming and outgoing lines in the closed state)

The undervoltage release coil is sourced from Jiangsu Guoxing, with the coil winding count meeting the standard
