China officially implemented mandatory CCC certification for all fuses on July 1, 2026, replacing the self-declaration model with strict third-party supervision. All products must finish certification conversion by December 31, 2026, while uncertified fuses will be banned from production and sales from 2027. As a leading manufacturer, Zhejiang Zhenghao Fuse has completed full CCC certification for photovoltaic, energy storage and industrial fuses, providing fully compliant and reliable fuse solutions for the new energy industry.

As the global energy structure accelerates its transformation to green and low-carbon, photovoltaic power generation, as an important part of renewable energy, has ushered in rapid development.

Recently, the 32nd China International Electric Power Equipment and Technology Exhibition opened grandly in Shanghai. This annual industry gathering brought together top global companies and cutting-edge technologies in the power sector. Among the numerous showcased products, fuses stood out as key equipment ensuring the safe and stable operation of power systems, captivating the attention of professional visitors and industry experts with their unique appeal.

The working principle of fuse is mainly based on the thermal effect of current and the physical properties of metal conductor expansion due to heat.

After working as an electrician for over a decade, my biggest fear is a sudden blown fuse in my equipment. Ordinary fuses are either slow to react or frequently trip. It wasn't until I used Zhenghao's 80A 22×58mm Cylindrical Fuse that these issues were completely resolved.

Overcurrent protection is the core safety barrier of all low-voltage industrial power distribution systems, and standard-compliant high-current fuses act as the first line of defense against short-circuit and overload faults that damage switchgear, motors and transformers. IEC 60269 415V High Current Fuse follows unified international IEC 60269 standards and adopts bolt-on ceramic construction to deliver stable gG/gL full-range protection for 415V AC industrial circuits. This article focuses on the core concerns of electrical engineers and procurement specialists, covering standardized structural design, full performance parameters, material durability, multi-industry application matching, installation specifications and fault response logic. All analysis avoids financial indicators, and centers on safety compliance, thermal stability, breaking capacity and long-cycle operational reliability to offer systematic reference for low-voltage power system configuration.
