Fuse; Power; Class RK5; Time Delay; 0.81x5 In.; 20 A; 600 VAC BUSSFRSR20

OVERVIEW

 

Features:

 

 

• Dual-element feature provides the best time-delay 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.
