Next-generation circuit breaker that instantly limits overcurrent.

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.

[Information] Shirutoku Report No. 68 # Types and Roles of Breakers

[Information] Shirutoku Report No. 68 # Types and Roles of Breakers

The breakers lined up in the distribution board are of different types according to their purposes!

★★Shirutoku Report: Useful Information You Should Know★★ The Power Supply Design Department designs various types of switching power supplies, such as AC-DC converters and DC-AC inverters, and conducts various evaluations and tests specific to power supplies. Among these tests, there are rigorous evaluations known as "abnormal tests," which assess safety during component failures. One of the important devices that protects the evaluation equipment during such harsh tests is the "circuit breaker." Many may be more familiar with the term "breaker." This report will introduce you to these breakers. 【Contents】 ■ Ampere Breaker: Maintains the current value contracted with the power company ■ Leakage Breaker: Protects commercial systems held by households and power companies from accidents ■ Safety Breaker: Maintains the current value for each circuit (each room) *For more details, please refer to the PDF document or feel free to contact us.
