A 600VDC ceramic body fuse has been introduced by Littlefuse - the 507 Series Cartridge Fuse has an interrupting rating of 150A at 650VDC in a 6x32mm package. Its high DC voltage rating, combined with current ratings from 1-8A, make it suitable for over-current protection in high-voltage DC power circuits.
As the power density that circuits must handle grows ever higher, these miniaturised high-voltage fuses are useful for DC power over-current protection.
The 507 Series Fuse is available in both standard cartridge and axial-leaded designs, is RoHS compliant and 100% lead free. Typical applications for the 507 Series include over-current protection for Variable Frequency Drives (VFDs), PhotoVoltaic (PV) inverters, DC/DC converters and high-voltage power supplies.
“We designed the 507 Series Fuse specifically for the needs of the industrial systems market,” said Tim Patel, Global Strategic Marketing Manager at Littelfuse for the Industry 4.0 market. “Our goal was to give circuit designers an option for delivering the highest possible power to motors while providing protection in the smallest possible footprint.”
