High-power applications in the industrial, automotive, and renewable energy sectors require robust overcurrent and short-circuit protection mechanisms to ensure safe and reliable operation. Bourns® POWrFuse™ High-Power Fuses are designed to meet the stringent UL 248, IEC 60269, and ISO 8820 standards and provide reliable protection in extreme ambient temperatures, high-cycling, and low-level fault current conditions.

POWrFuse™ High-Power Fuses are available in various mounting configurations to accommodate customers’ design requirements. They are rated at extremely high interrupting currents and are classified into five categories: Photovoltaic (Class gPV), Semiconductor (Class aR), Industrial, Telecom, and Electrical Vehicles (EVs). This ensures that the appropriate fuse link can be selected based on the application’s requirements.

The Photovoltaic and Semiconductor categories are designed to protect the high-power inverters and solar panels from overcurrent and short-circuit conditions. These fuses are available in compact sizes and are ideal for use in solar farms and other renewable energy applications.

The Industrial category is designed for use in high-power distribution systems and machinery, where high-interrupting currents are a requirement. The Telecom category is designed to provide reliable protection to telecommunication equipment such as base stations and data centers. Finally, the EV category is designed to protect electric vehicle batteries and charging systems from overcurrent and short-circuit conditions. In addition to POWrFuse™ High-Power Fuses, Bourns® offers a complete line of overvoltage protection products such as Surge Protective Devices (SPDs), Power TVS Products (PTVS Diodes), High Energy MOVs, and High Current GDTs. This complete circuit protection solution can be installed in the most demanding applications, providing an additional level of protection against transient overvoltages.

Bourns® POWrFuse™ High-Power Fuses are an integral part of any high-power application that requires reliable overcurrent and short-circuit protection. Their ability to withstand extreme ambient temperatures, high-cycling, and low-level fault current conditions make them the ideal choice for industrial, automotive, and renewable energy applications. With various mounting configurations and categories to choose from, Bourns® POWrFuse™ High-Power Fuses provide an effective solution to protect your critical equipment from damage and ensure the safety of personnel.
