Bussmann FRS-R-6 Dual Element Time-Delay Fuses

• Dual-element feature provides the best timedelay performance, allowing closer sizing and superior protection of motors and transformers
• Closer sizing allows for smaller fuses and less costly switches
• Class RK5 fuses with a 200 kA interrupting rating for use in a broad range of applications
• Provides motor overload, ground fault, and short-circuit protection
• Helps protect motors against burnout from overloads and single-phasing when sized properly
• Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short-circuit and overload protection
• Offers a 10-second 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. Considerable cost savings occur by permitting the use of smaller size switches, panels, and fuses themselves.
• Provides current limitation to help protect downstream components from high fault currents.
• Gives motor running back-up protection to motors without extra costs.
