MCCB Highlights

ARXM3 series thermal magnetic type mccb advantages:

Advanced Surface Treatment: Surface treatment and processing technology of mechanism parts: QPQ heat treatment technology imported from Germany.
Rigorous Testing: We selected the operating mechanism (steel) of AceReare Electric and another brand sample to compare the experimental results.
Superior Hardness: The operating mechanism of AceReare Electric has a hardness of 366.1, while the hardness of the other brand is only 252.6, which cannot even reach our lowest value.

The mechanical life and electrical life are very important indicators in the national standard of the circuit breaker, and our circuit breaker operating mechanism needs to reach a certain strength and hardness, so that the circuit breaker will not damage the service life of the circuit breaker in the opening and closing process, while the hardness of the other brand is far lower than the CQC standard.

Frequently Asked Questions (FAQ)

What core technology is used in the ARXM3 series MCCB mechanism parts?

The mechanism parts of the ARXM3 series thermal magnetic type MCCB utilize advanced QPQ heat treatment technology imported from Germany for superior surface treatment and processing.

How does the hardness of AceReare Electric's operating mechanism compare to other brands?

In experimental comparisons, the operating mechanism of AceReare Electric achieved a hardness rating of 366.1, whereas the competitor brand only reached 252.6, which fails to meet even our minimum requirements.

Why are mechanical and electrical life ratings important for circuit breakers?

They are vital indicators within the national standard for circuit breakers. High mechanical and electrical life ensures that the operating mechanism has the strength and hardness to perform opening and closing cycles without premature damage.

Does the competing brand's MCCB meet CQC standards for hardness?

No, the testing shows that the hardness of the other brand's operating mechanism is significantly lower than the CQC standard, which can negatively impact the overall service life of the circuit breaker.

What materials and components were compared in the hardness experiment?

The experiment evaluated and compared the steel operating mechanisms of AceReare Electric and another brand sample to determine their respective strength and hardness levels.
