Littelfuse, Inc., a global leader in circuit protection solutions, has recently launched a range of high-voltage fuse blocks and holders designed for mechanical mounting. These new products are specifically engineered for applications operating between 400V and 600V, offering flexible mounting options that align with various system designs. The design is optimized to support on-site repairs in environments where transportation costs are high or equipment downtime must be avoided, while also ensuring the safety of maintenance personnel during fuse replacement.
The new product line includes:
- **354, 254, and 520 Series OMNI-BLOK® Fuse Blocks** for 3AB/3AG, 2AG, and 5x20mm fuses respectively
- **356/359 Series Screw Terminals and Laminated Base Terminals** for 3AG/3AB fuses
- **345 Series Shock-Proof Circuit Board and Panel Mount Enclosed Fuse Holder** for 3AG/3AB and 5x20mm fuses
- **150 Series Leaded Fuse Holder** for 3AG/3AB fuses
- **HBC Series High-Voltage Fuse Box and Fuse Holder**
These components are ideal for use in data centers (for UPS and servers), building automation systems (fan control and commercial HVAC), industrial power systems (UPS, voltage regulators, battery systems, and power distribution units), as well as commercial appliances such as air conditioners, ventilation systems, dryers, irons, and washing machines.
Ben Zhang, Product Manager at Littelfuse, said: “These new high-voltage fuse blocks and holders are compact, similar in size to their low-voltage counterparts, allowing high-voltage performance without increasing the overall footprint.â€
Key benefits of the new fuse boxes and holders include:
- High voltage ratings ranging from 400V to 600V, with multiple mounting options for diverse applications
- Wide operating temperature range (-40°C to +85°C) for reliable performance in harsh environments
- Halogen-free, 100% lead-free, and RoHS-compliant materials, supporting eco-friendly designs and compliance with international standards
