N-SOG type high-pressure automatic branching low-voltage device for circuit breakers
CE-C105-DI
By monitoring zero-sequence current and zero-sequence voltage, we detect ground faults and overcurrent incidents that occur within the consumer's premises.
Generally, at the boundary point of safety responsibility for high-voltage consumers, it is stipulated to install SOG-type high-voltage automatic branch circuit breakers to prevent accidents occurring within the high-voltage consumer's premises from affecting the distribution lines. This device is used in combination with the SOG-type high-voltage automatic branch circuit breaker to detect ground faults and overcurrent incidents occurring within the consumer's premises by monitoring zero-sequence current and zero-sequence voltage.

basic information
■□■Features■□■ ■Ground Fault Detection Operation When a ground fault incident is detected, the direction of the ground fault is determined. If it is judged to be on the inside of the facility, the circuit breaker will be opened by trip output (GR operation). ■Overcurrent Detection Operation When an overcurrent incident is detected within the facility, after the power side of the high-voltage circuit is de-energized, the circuit breaker will be opened by overcurrent accumulation trip output (SO operation). ■Ground Fault Operation Setting The setting of the ground fault operation current and the setting of the ground fault operation time can be configured. ■Abnormal Detection Function The internal circuits of the device are regularly self-diagnosed, and if an abnormality is detected, trip output is prohibited. Similarly, if a trip coil disconnection of the circuit breaker is detected, trip output is also prohibited. ■For more details, please contact us.

Company information
Our company was founded in 1949 as a designated manufacturer of wire materials by the Ministry of Telecommunications. We have steadily established our presence by designing and manufacturing telephone and communication systems and related equipment for public enterprises such as police, railways, electricity, and broadcasting, alongside the development of related companies. We also have a significant track record in OEM products for major manufacturers. Our main products are custom-made items, which we handle from design to manufacturing, focusing on systems and products related to information and communication. Recent key products include disaster prevention information systems (JR East and JR Hokkaido), command telephone systems (various JR companies, electricity companies, and private broadcasters), remote monitoring and control systems (various JR companies, electricity companies, and telecommunications carriers), and emergency contact systems (private elementary and junior high schools). Currently, we are working on the development of the latest IT and IP systems, such as serverless IP conference call systems, to respond to the evolution of communication networks. If you present us with challenges in niche areas where major manufacturers are not proficient, we are committed to leveraging our years of accumulated experience and the latest technology to provide low-cost and quick delivery solutions. We appreciate your guidance and support.
