The M‑series circuit breakers are new‑generation intelligent moulded‑case circuit breakers developed by AEG after years of R&D, tailored to the application habits and requirements of the Chinese market. Widely applied in power generation, industry, shipbuilding, petrochemical, building construction and other sectors, they serve for power distribution and control in low‑voltage systems.
This series covers a current range from 3 A to 630 A, including 3‑pole and 4‑pole versions.
Multiple installation types are available: fixed‑type, plug‑in type and draw‑out type, together with a full range of accessories.
The series comprises three frame sizes, each complying with the requirements relevant to its intended applications.
Product Performance and Parameters

Electromagnetic Compatibility
The operating temperature range for the M-series molded case circuit breaker is -20 ° C to+70 ° C. If it is used above 40 ° C, it must be used in combination for the following two basic reasons: Prevent the materials that make up the mechanical/electrical properties of the circuit breaker from reaching temperatures that affect their characteristics. For the breakage of the thermal magnetic release device, the bimetallic strip with the action characteristics generated by overcurrent has a significant impact on the action characteristics at higher ambient temperatures (premature release). The normal storage temperature for M-series molded case circuit breakers is -40 ° C to+85C ° C

Vibration and Vibration
When subjected to random vibrations with an amplitude of 0.29g/Hz and a range of 5H to 500Hz (3dB corner point,+20dB/decimal decay) for 30 minutes, the experiment operates normally and undergoes three axis vibrations.
