Carton Quantity and Weight Amp Rating Carton Qty. 1 ⁄10–15 10 171⁄2–30 10 35-60 10 Dimensions - in Features: • Provides motor overload, ground fault and short-circuit protection. When used in circuits subject to surge currents such as those caused by motors, transformers and other inductive components, these fuses can be sized close to full-load amps to give maximum overcurrent protection. • Permits the use of smaller and less costly switches. The time-delay feature makes it possible to use fuse amp ratings which are much smaller than those of non-time delay fuses. Considerable cost saving occurs by permitting the use of smaller size switches, panels and fuses themselves. • Provides a higher degree of short-circuit protection (greater current-limitation) in circuits in which surge currents or temporary overloads occur. • Helps protect motors against burnout from overloads • Gives motor running back-up protection to motors without extra costs • Helps protect motors against burnout from single phasing on three phase systems • Simplifies and improves blackout prevention (selective coordination) • 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 • The overload element provides protection against low level overcurrent of overloads and will hold an overload which is five times greater than the amp rating of the fuse for a minimum of ten seconds Recommended Fuse Blocks Fuse Amps 1-Pole 2-Pole 3-Pole 0-30 R60030-1 R60030-2 R60030-3 35-60 R60060-1 R60060-2 R60060-3 For additional information on the R600 Series of 600 volt fuse blocks, see Data Sheet # 1111.
