Bourns, Inc has expanded the its POWrFuse High-Power Fuse product family. The two new models PF-F and PF-M series are high power rating industrial fuse links specially created to meet the UL 248-13 semiconductor (aR) standard. These high power fuses are ideal solutions to help protect sensitive power semiconductor devices against overcurrent events in various power inverters, converters, AC/DC drives, rectifiers, UPS systems and reduced voltage motor starters.
The PF-F series features 800VAC/VDC voltage, power ratings from 50-400A and up to a 100kA @ 800VAC and 50kA @ 800VDC interrupting rating. The PF-M series provides 240VAC/150VDC voltage, power ratings from 50-180A and up to a 160kA @ 240VAC and 50kA @ 150VDC interrupting rating. Both of these high-power fuse series are bolt mounted, offer fast-acting protection under fault current, low resistance and power loss, and deliver an operating temperature range of -55C to +125C.
Also, these series are UL recognised to help OEMs save qualification time while also increase overall quality and reliability. These attributes, in turn, help to lower the total cost of ownership for end customers.
The series are available now and are RoHS compliant* and halogen-free.
