住電機器システム List of Products and Services

This product is a bus duct with a structure that maintains a spatial distance between the bare conductors and between the conductors and the housing (air insulation), making it resistant to insulation degradation. The conductors are supported by insulation with excellent electrical properties and sufficient mechanical strength, ensuring safety. Due to the relatively easy-to-remove plug-in holes, it is suitable for situations with many load branches, such as factory production lines. 【Features】 ■ High reliability ■ Long lifespan ■ Advantageous for layout changes and load branching *For more details, please refer to the PDF document or feel free to contact us.

• Wiring devices

This product is an insulated bus duct that employs insulated conductors with a polyester sheet (PET) coating, ensuring excellent electrical and mechanical performance. By using "SS nuts," which have a function that allows visual confirmation of the completion of tightening at the bus duct connection points, it prevents forgetting to tighten the connections, eliminating the need for re-tightening inspections. The connection points have a symmetrical structure, making them non-directional and providing excellent workability for layout changes and other adjustments. 【Features】 ■ High reliability ■ Excellent workability ■ Compact design ■ Supports large current capacity ■ Eco-friendly *For more details, please refer to the PDF document or feel free to contact us.

• Wiring devices

The "Plug-in Switch (PSW type)" can be easily, safely, and reliably inserted into the plug-in hole (PH) of the bus duct body to create a branch. With years of experience and technical expertise, we have developed and improved the contact structure to ensure stable contact force. The circuit breakers include general-purpose (NFB) types, high-performance products, ultra-current limiting circuit breakers, and earth leakage circuit breakers (ELB), among others, and we also accommodate other options. 【Features】 ■ Easy load branching ■ High reliability ■ Capable of large capacity load branching ■ Flexible design support ■ Live working is also possible *For more details, please refer to the PDF materials or feel free to contact us.

The "Tap Off Switch (TSW Type)" is designed with a tap hole (TH) in the bus duct body, allowing for reliable load branching by bolting this product. By securely bolting the tap-off bar, long-term reliability has been achieved. In addition to standard designs, we also accommodate external handle-operated types and special designs tailored to site conditions. 【Features】 ■ Capable of large capacity load branching ■ High reliability ■ Flexible design support *For more details, please refer to the PDF document or feel free to contact us.

• Wiring devices

The "Mini Bus Duct (MBD Type)" is a power supply system suitable for low-capacity branch main lines in factory production lines and similar applications. The installation of plug-in devices can be done with a single touch, and the grounding of the case and plug-in switch is done through a plug-in method, allowing for automatic bonding simply by setting it in place. It is compact and lightweight, allows for many branches, and is easy to relocate and expand, with a significant track record of deliveries to automotive factories and similar facilities. 【Features】 ■ Uses circular conductors to enhance overall rigidity ■ Stable connection with plug-in switches ■ Reliable and safe easy connection ■ Case grounding is automatically bonded with the installation of the connection cover ■ Allows for many branches *For more details, please refer to the PDF materials or feel free to contact us.

This catalog introduces the "cable fire prevention products" handled by Sumitomo Electric Device Systems. In mid- to high-rise buildings such as offices, apartments, and hotels, there are construction methods for fire prevention measures at cable fire penetration points to prevent the spread of fire. When penetrating the walls and floors of fire prevention compartments, it is stipulated by the Building Standards Act that they must be "certified by the Minister of Land, Infrastructure, Transport and Tourism," and we have listed products and materials that have obtained this certification. [Contents] ■ 1. Minister of Land, Infrastructure, Transport and Tourism certified construction methods ■ 2. Materials for cable fire compartment penetration treatment ■ 3. Cable fire spread prevention materials ■ 4. Spark prevention sheets (HB sheets) ■ 5. About construction method labels *For more details, please refer to the PDF document or feel free to contact us.
