Fuji Electric Machine Control (Headquarters in Tokyo) has launched the "G-TWIN" series of wire breakers and earth leakage breakers, designed to meet global standards. These products are tailored for international markets, offering a wide range of specifications including IEC (Europe), New JIS (Japan), CCC (China), and UL489/cUL (US & Canada). In addition, some models support three major standards beyond UL489/cUL, making them highly versatile for global applications.
The G-TWIN series includes standard circuit breakers priced between 28,970 and 590,600 yen, while earth leakage breakers range from 820,000 to 1,614,000 yen. This variety ensures that customers can choose the most suitable product based on their specific requirements.
Traditionally, manufacturers have faced challenges in designing and managing inventory for different regional standards. The G-TWIN series addresses this by consolidating multiple specifications into a single, unified design. This not only streamlines the design process but also significantly reduces inventory costs and complexity.
One of the key innovations in the G-TWIN series is the use of arc flow control technology, which enhances safety and performance. The compact design meets the smallest IEC and New JIS specifications globally, with a volume that is 53% smaller than the previous 250A model. Additionally, the arc energy generated during tripping is reduced by 30%, improving overall reliability.
Another notable feature is the built-in "Megatest switch," which simplifies testing procedures. During insulation resistance tests, there's no need to disconnect the wiring of the earth leakage breaker, saving time and effort. Furthermore, the system is capable of detecting leakage even when a fault occurs in one phase of a three-phase circuit, in compliance with IEC standards.
Overall, the G-TWIN series represents a significant advancement in electrical protection solutions, offering flexibility, efficiency, and enhanced safety for global applications.
