Helps protect motors against burnout from overloads andsingle-phasing when sized properly. Simplifies and improves blackout prevention (selectivecoordination). Dual-element fuses can be applied in circuits subject totemporary motor overloads and surge currents to provideboth high performance short-circuit and overloadprotection.
2 The overload element provides protection against low levelovercurrent of overloads and will hold on inrush currentwhich is five times greater than the amp rating of the fusefor a minimum of ten - inCarton Quantity and WeightAmpCartonWeight* *Weight per Reducers For Class R FusesEquipmentDesired FuseCatalog NumberFuse Clips(Case) Size(Pairs) 250V200A100 ANo. 2621-R400A100 ANo. 2641-R200 ANo. 242-R100 ANo. 2661-R600A200 ANo. 2662-R400 ANo. 2664-R**Single reducer only (pair not required).Catalog Symbol: FRN-R Current-LimitingDual-element, time-delay 10 seconds (minimum) at 500%rated currentAmp Rating: 70 to 600 AVoltage Rating: 250 Vac (or less)125 Vdc (110-200A)250 Vdc (225-600A)Interrupting Rating:200,000A RMS ,000A dc Agency Information: CE, UL Listed, Std.
