Fuse Blocks and Holders are RoHS compliant.

Wide range of applications in data centers, building automation, industrial power systems, and commercial appliances

Littelfuse, Inc., the global leader in circuit protection, today introduced multiple series of high-voltage Fuse Blocks and Fuse Holders designed for mechanical installation of fuses. Developed for applications from 400 volts to 600 volts, these new series include several fuse mounting alternatives to accommodate the mechanical design of the application. They are optimized for field servicing of equipment that is costly to move or for which downtime is unacceptable, while ensuring the safety of maintenance personnel by preventing electrical shocks when fuses must be replaced in the field. The new product series include:

  • 354, 254, and 520 Series OMNI-BLOK® Fuse Blocks for 3AB/3AG, 2AG, and 5x20mm Fuses respectively
  • 356/359 Series Screw Terminal and Laminated Base Terminal for 3AG/3AB Fuses
  • 345 Series Shock-safe Circuit Board and Panel Mount Enclosed Fuse Holders for 3AG/3AB and 5x20mm Fuses
  • 150 Series In-Line Holders for 3AG/3AB Fuses

Application areas include data centers (for UPSs and servers), building automation (for fan control systems, commercial HVAC), industrial power systems (for UPSs, voltage regulator modules, high power battery systems, and power distribution units and base station power supplies), and commercial appliances (such as air conditioners, commercial ventilation systems, drying and ironing rolling presses, and industrial washing machines).

“These new higher voltage fuse blocks and holders offer the same miniature form factors as the lower voltage versions,” said Ben Zhang, Product Manager at Littelfuse. “This eliminates the need to compromise on size to get higher voltage performance.”

The new Fuse Holders and Fuse Blocks offer a variety of key benefits:

  • High voltage ratings from 400V to 600V and multiple fuse placement options offer a complete fuse/holder solution for high voltage application requirements.
  • Wide operating temperature range (-40°C to 85°C) makes them suitable for use in a diverse variety of applications and harsh operating environments.
  • Halogen free, 100% lead-free and RoHS compliance provides designers with confidence that they are environmentally friendly and comply with global regulations.

The company serves customers in the electronics, automotive, and industrial markets with technologies including fuses, semiconductors, polymers, ceramics, relays, and sensors. Littelfuse has over 10,000 employees in more than 40 locations throughout the Americas, Europe and Asia. 

Littelfuse offers innovative circuit protection solutions. Wherever you look, Littelfuse is there. Streetlights, office buildings, cars, trucks, factories, computers, heating and cooling systems, electronic games, telecommunications equipment, even the satellites in the sky are protected by Littelfuse circuit protection products.Littelfuse was founded in 1927 by Edward V. Sundt. Sundt invented the first small, fast-acting protective fuse to prevent sensitive test meters from burning out. From that pioneering first step, the company has gone on to define the standards of the circuit protection industry. In the 1960s, Littelfuse developed sub-miniature fuses for NASA, which were mission-critical components of the American space program. And in 1976, it introduced the groundbreaking Autofuse® Fast-Acting Fuse for General Motors. Within eight years, it was being designed into vehicles all over the world and has been developing industry-leading circuit protection products by working clo...
