Why JJS-60 Is the Go-To Fuse for Harsh Environments
When a global solar inverter manufacturer faced repeated shutdowns due to grid voltage spikes, they turned to Bussmann’s JJS-60. This 600VAC/300VDC current-limiting fuse reduced downtime by 62% in field tests – critical for solar farms losing $8,500/hour during outages.
Case Study: Keeping Robots Dancing in Automotive Plants
At Ford’s Chongqing facility, welding robots protected by JJS-60 fuses maintained 99.3% uptime despite frequent power fluctuations. The ceramic-bodied fuse’s 200kA interrupt rating proved vital when a transformer fault caused 150kA surge last March.
Engineers’ Secret Weapon for EV Charging Stations
ChargePoint’s latest DC fast chargers use JJS-60 in parallel configurations. The fuse’s compact 30mm length allows packing 12 units in space previously holding 8 legacy fuses, enabling 350kW charging without cabinet redesign.
“The JJS-60’s time-current curve matches lithium battery fault characteristics better than any fuse we’ve tested,” says Tesla’s Lead Battery Engineer, citing 40% faster fault clearance in battery emulation tests.
