Next-generation circuit breaker that instantly limits overcurrent.

Minimizing overcurrent, it automatically enters current limiting and interruption operation, completing the interruption in a short time.

This technology is a power circuit breaker that adopts a completely new operating principle, not an extension of conventional technology. By highly integrating fuses and semiconductor switches, it enables the realization of a "next-generation circuit breaker" that can instantly limit overcurrent. - It can reliably prevent and completely interrupt abnormal large currents every time. - It allows for immediate current limiting and interruption (AC, DC, overcurrent). - High-speed re-energization is possible. - High versatility (operating voltage 0.1 to 10 kV). - High design flexibility makes optimization for various applications easy. Comparison with existing circuit breakers for railways: - Interrupt time (approximately 40% shorter). - Device size (approximately 95% smaller). - Price (approximately 90% reduction). By dramatically reducing the risk of electrical equipment failure and minimizing current resistance, benefits such as miniaturization and cost reduction of electrical systems can be expected.
