Product Description

Bussmann FRN-R-110 – 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
