MCCB Highlights

ARXM3 series thermal magnetic type MCCB advantages

🇩🇪 Surface treatment and processing technology of mechanism parts

QPQ heat treatment technology imported from Germany

🔬
1. Comparative Experimental Testing We selected the operating mechanism (steel) of AceReare Electric and another brand sample to compare the experimental results.
📈
2. Hardness Performance Analysis 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 is the main advantage of the ARXM3 series MCCB operating mechanism?

The ARXM3 series utilizes German-imported QPQ heat treatment technology for the surface treatment and processing of its steel mechanism parts, ensuring high strength and hardness.

❓How does AceReare Electric's mechanism hardness compare to other brands?

AceReare Electric's operating mechanism achieves a hardness rating of 366.1, whereas the tested competitor brand reached only 252.6, which fails to meet even our minimum internal baseline.

❓Why are mechanical and electrical life critical for circuit breakers?

They are key indicators in national circuit breaker standards. A robust operating mechanism prevents wear and damage during the opening and closing processes, preserving the overall service life of the device.

❓Do competitor brands meet the CQC standard for MCCB hardness?

Based on our comparative tests, the hardness of the competitor brand's operating mechanism is far lower than the CQC standard, whereas AceReare Electric's mechanism is engineered to exceed standard requirements.

❓What technology ensures the durability of the ARXM3 MCCB?

The durability is achieved through premium steel selection and the application of imported German QPQ heat treatment, which significantly enhances the mechanical properties of the operating mechanism.
