The low-voltage fuse "SBFC-ET" is a slow blow fuse that can withstand temporary overcurrents and only blows under continuous overcurrents. It is particularly effective for devices in automobiles where the current temporarily increases significantly. It is suitable for fuel pumps, washer pumps, and similar applications. This low-voltage fuse is recommended for those facing circuit protection challenges in the automotive industry, construction machinery industry, and for low-voltage fuses (below DC70V).

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
