Bourns, Inc. has expanded its POWrFuse High-Power Fuse portfolio with a new higher voltage rated series.
Bourns engineered the PF-63R50H Series with advanced features and capabilities that are needed in energy storage systems, battery systems, and other types of power management systems.
“The increasing demand for higher power density and improved system efficiency, particularly in energy storage systems, industrial automation, and renewable energy applications, is accelerating the need for power fuses with higher voltage and current ratings,” said Jennifer Joseph, Vice President of Bourns Protection Division. “Our new PF-63R50H Series POWrFuse is specifically designed to align with and support these evolving market requirements.”
Meeting UL 248-14 and IEC 60127-1 fuse standards, the PF-63R50H Series features current ratings from 10 to 40A, an interrupt rating of up to 30kA, and is available in cartridge and axial lead options. These features support broader application needs and provide additional R&D flexibility while also meeting system performance and safety requirements.
The Bourns PF63R50H Series POWrFuse High-Power Fuses are available now through Bourns’ authorised distribution partners, and are RoHS compliant and halogen free.
