Bussmann FRS-R-20 Fuse

Bussmann FRS-R-20 Energy Efficient Time-Delay Fuse, 20 A, 600 VAC, 300 VDC

• Dual-element feature provides the ideal time delay performance, allowing closer sizing and excellent protection of motors and transformers
• Closer sizing allows for smaller fuses and less costly switches
• Provides motor overload, ground fault and short circuit protection
• Helps protect motors against burnout from overloads and 1-phase when sized properly
• Offers a 10 secs time delay at 5 times the rated current
• The time delay feature makes it possible to use fuse amp ratings that are much smaller than those of non-time delay fuses
• Provides current limitation to help protect downstream components from high fault currents
• Gives motor running backup protection to motors without extra costs
