Frs-r-400 bussmann fuse 400 amp 600 volt time delay
Current-Limiting, dual-element, time-delay 10 seconds
(minimum) at 500% rated current
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.
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 good degree of short-circuit protection (greater
current-limitation) to help protect downstream components
Gives motor running back-up protection to motors without
Helps protect motors against burnout from overloads and
single-phasing when sized properly.
Simplifies and improves blackout prevention (selective
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.
