The 500ADC Circuit Breaker Tester from Wuhan GDMK Electric Co., Ltd. is engineered for testing DC circuit breakers with a rated current range of 1A to 500A. It features a 320x240 LCD screen with a thermal printer, interactive keyboard, and an intelligent operation system that allows standalone use or PC connectivity. Power electronics control enables high-current output with precision and continuous adjustability, while multiple high-precision sensors automatically switch current ranges.
The tester incorporates a 14-digit high-capacity AD acquisition chip for accurate data capture and can store up to 200 test results without data loss during power failure. It supports two testing modes: ampere-second characteristic tests and through-current characteristic tests. When connected to a PC, it facilitates instrument control, data import, saving, report generation, and graph plotting. Protection features include safeguards against overheat, over-current, and over-voltage, with strong electromagnetic compatibility for reliable performance in industrial environments.
This equipment is used by electrical maintenance teams, testing laboratories, and industrial plants to verify circuit breaker performance under real-world conditions. Buyers typically include utilities, manufacturing facilities, and service providers requiring precise DC breaker validation. The unit operates as a standalone device or integrates into automated test benches, with options for custom calibration and software updates to match evolving standards.

Before ordering, verify the tester’s compatibility with your circuit breaker models and current ratings. Confirm whether the 1A-500A range aligns with your testing needs, and check if additional calibration or software updates are required for your specific applications.
For logistics, clarify Incoterms (e.g., FOB Wuhan) and lead times, as the supplier’s harbor-tier status may imply variable production schedules. Payment terms should be confirmed in advance, with preference for secure methods like TT or L/C. Request packaging details to ensure safe transit, especially for sensitive electronic components.
Quality checks should include validating the tester’s accuracy against known standards (e.g., IEC 60947 for breakers). Inspect the unit for EMC compliance and protection features upon arrival. Ensure the supplier provides a test report or certificate for the 200-result storage capability and thermal printer functionality. Documentation should include user manuals and calibration certificates.
