Bourns adds Class aR model to its POWrFuse Family 

Fuse links specifically designed to meet UL 248-13 standard for high power, high interrupting and high current rating applications expand Bourns’ POWeFuse family. 

The  PF-F and PF-M series are high power rating industrial fuse links specially designed to meet the UL 248-13 semiconductor (aR) standard. They help protect sensitive power semiconductor devices against overcurrent events in a variety of power inverters, converters, rectifiers, AC/DC drives, UPS systems and reduced voltage motor starters.

The Bourns POWrFuse PF-F series features 800V AC / V DC voltage, power ratings from 50 to 400A and up to a 100kA at 800V AC and 50kA at 800V DC interrupting rating. The POWrFuse PF-M series provides 240V AC / 150V DC voltage, power ratings from 50 to 180A and up to a 160kA at 240V AC and 50kA at 150V DC interrupting rating. 

Both of these high-power fuse series are bolt mounted, to protect from under fault current, low resistance and power loss. Operating temperature range is -55 to +125 degrees C.

Both series are UL-recognised to help save qualification time.

Both the PF-F and PF-M are available now. They are RoHS-compliant and halogen-free.

Bourns manufactures and supplies position and speed sensors, circuit protection solutions, magnetic components, microelectronic modules, panel controls and resistive products. Headquartered in Riverside, California, USA, Bourns serves a broad range of markets, including automotive, industrial, consumer, communications, medical (low/medium risk) and audio market segments.
