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 instant current limiting and interruption (AC, DC, overcurrent). - High-speed re-energization is possible. - High versatility (operating voltage 0.1 to 10 kV). - Due to high design flexibility, optimization for specific applications is easy. Comparison with existing circuit breakers for railways: - Interrupt time (approximately 40% reduction). - Device size (approximately 95% miniaturization). - Price (approximately 90% reduction). By dramatically reducing the risk of electrical equipment failure and improving current resistance, benefits such as miniaturization and cost reduction of electrical systems can be anticipated.

Explosion isolation device

Explosion isolation device

Providing customized solutions for achieving dust-free and safe production!

The explosion isolation device is a passive one-way explosion-proof valve used in piping that contains combustible dust, allowing dust and gas to pass through the piping in only one direction, thereby preventing the reverse propagation of explosions. Proper use of the explosion isolation device can prevent the spread of dust explosions from downstream piping to upstream piping, effectively avoiding secondary explosions and multiple explosions, preventing the escalation of dust explosion accidents, and protecting the safety of people and property.

Circuit breaker for distribution boards and control panels <spring clamp terminal specification>

Circuit breaker for distribution boards and control panels <spring clamp terminal specification>

Protection level IP20, no terminal cover required! Lineup up to rated current of 50A.

We have added a spring clamp terminal specification to our lineup of circuit breakers for distribution boards and control panels, the "KC Series (NF50-KC, NV50-KC)." This specification eliminates the need for skills in screw tightening work, reducing the risk of terminal screw loosening due to vibration, impact, and long-term use. There is no need for re-tightening work during the delivery and inspection of panels and machinery. The spring clamp terminal specification contributes to "reduced construction work," "stable quality," and "improved maintenance." 【Features】 ■ Possible reduction in wiring work time ■ No terminal cover required ■ No need for re-tightening work during the delivery and inspection of panels and machinery ■ Spring clamp terminal specifications can be accommodated for one side only, such as primary side screw terminals and secondary side spring clamp terminals ■ Specifications for spring clamp terminals can also be accommodated for only the included terminal blocks *For more details, please download the PDF or feel free to contact us.
