Separate overload and short circuit elements provide time delay for sizing as close as 125% of motor FLA
2:1 selective coordination amp ratio (within the cooper Bussmann RK5 fuse family) prevents overcurrent events from opening upstream Fusetron™ fuses
Provides motor overload, ground fault and short circuit protection
Helps protect motors against burnout from overloads and single phasing when sized properly
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 ampere rating of the fuse for a minimum of ten seconds
200 kA (RMS symmetrical) at 250 VAC, 20 kA at 125 VDC interrupt rating
10 sec (minimum) at 500% of rated current time delay
