- Features
| Ind Facilities & Factories - Facility: Safety and Security Systems |
| 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 on 3-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 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 |
