Product Description
Bussmann FRN-R-250 - 250 Volt, Dual-Element, Time Delay Fuse
- Provides motor overload, ground fault and short-circuit protection.
- Helps protect motors against burnout from overloads.
- 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 ampere rating of the fuse for a minimum of ten seconds.
- Current-Limiting, Dual-Element, Time-Delay: 10 seconds (minimum) at 500% rated current
- Ampere Rating: 70 to 600 A
- Voltage Rating: 250Vac (or less), 125Vdc (70-200A), 250Vdc (201-600A)
- Interrupting Rating: 200,000A RMS Sym., 20,000 AIC
- DC Ratings: 20,000 AIC @ 125 VDC
- Agency Information: UL Listed, Std. 248-12, Class RK5, Guide JDDZ, File E4273, CSA Certified, C22.2 No. 248.12, Class 1422-01, File 53787
