The RAPIDPLUS® SQB Square‑Body aR fuse links are high‑speed semiconductor fuses engineered by DF Electric for protection of power electronic components. Available in a wide current range they support AC voltages up to 690 V. Designed for high fault-current interruption, they feature either M8 flush-end threaded contacts or robust blade contact options (80 mm or 110 mm) to ensure reliable connection in both panel-mounted and busbar systems. Their operating temperature span of –25 °C to +60 °C makes them suitable for demanding industrial environments. Each fuse is compact yet capable of clearing high-energy fault conditions, making them ideal whenever semiconductors like diodes, thyristors, IGBT modules, or triacs are used.
These SQB fuses safeguard critical components in equipment such as motor drives, photovoltaic inverters, welding power supplies, UPS systems, and high-power rectifiers. The square-body design allows optimised integration into panel fuse holders, offering low I²t to protect sensitive semiconductor devices with minimal energy let-through. With a high breaking capacity and fast acting characteristics, they prevent cascading failures in voltage conversion systems, ensuring safe, reliable operation and ease of replacement across a broad range of current ratings.
Have you ever wondered if there's any difference between cable coils and cable reels?
Our cable experts take you through the advantages of using cable coils.
What tri-rated cable are you currently using? Does the product or service you receive leave you wanting more? It’s time to ask the question. Because now, you’ve got options.
This innovative push-in connection system enables time savings of up to 50%, whether you're wiring control panels or managing complex installations
Solar energy has become a pillar of the global energy transition. The experts at OEM Automatic have broken down the role of photovoltaic fuses and their contribution to solar systems, as well as, how to choose the right solution for you.
Ultra fast-acting fuse links engineered specifically to shield delicate semiconductor devices.
