Bussmann FRS-R-100 100 Amp Fusetron Dual Element Time-Delay Current Limiting Class RK5 Fuse, 600V UL Listed,Black

Product Description The Bussmann series FRS-R-100 is an energy effcient, dual-element, time-delay Class RK5 fuse and is part of our FUSETRON line of fuses. Its dual-element design provides the best time-delay for better protection of equipment such as power panelboards, combination starters, motor control centers, machinery disconnects, and safety switches. Dual element fuses feature separate overload and short-circuit elements to provide the same short circuit protection as a fast acting fuse with the added benefit of letting inrush currents pass without opening the fuse. As a time-delay fuse, it allows for temporary overload conditions without opening (sometimes called blowing a fuse). This is necessary for equipment that regularly experiences short-term power surges, such as when a motor or transformer strarts up. The time-delay feature allows an inrush current from the motor or transformer to start without opening but still protects against sustained overloads and short circuits. This also allows you to reduce the need to replace expired due to normal inrush overloads. For superior electrical protection, we recommend upgrading to Bussmann series Low-Peak LPS-RK fuses. From the Manufacturer FRS-R-100, RK5, FRS-R Fuse, 100A, 600VAC/300VDC, Bussman provides high quality products that are used in many applications including the foodservice industry

• 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
• 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
• Provides a good degree of short-circuit protection (greater current-limitation) to help protect downstream components from high fault currents
