The Linear 2500-1742 is a 6 amp slow-blow fuse for select Linear / OSCO gate operator circuits. A slow-blow fuse is used where the equipment may draw a brief starting surge, but the circuit still needs protection from a sustained fault. In gate operator service, the fuse should be treated as a protection device, not as the root problem by itself. If it blows repeatedly, the operator needs diagnosis before more fuses are installed.
This part is commonly listed as a 6 amp slow-blow fuse and some references associate it with OSCO SWD gate operator applications. Always match the fuse rating, physical style, and circuit requirement from the wiring diagram or original fuse label.
Commonly associated with these applications when the wiring diagram or parts list specifies 2500-1742:
| Manufacturer | Linear / OSCO |
|---|---|
| Product Type | Slow-blow fuse |
| Part Number | 2500-1742 |
| Application | Electrical circuit protection |
| Fuse Rating | 6 amp |
| Fuse Type | Slow-blow / time-delay style |
| Compatible Operator Type | Select Linear / OSCO operators and OSCO SWD applications where specified |
| Notes | Match fuse rating, style, and wiring diagram before replacement |
If the fuse blows again after replacement, stop and troubleshoot the circuit. Repeated fuse failure usually means another problem exists, such as a short, bad accessory, damaged wiring, motor issue, or incorrect fuse type.
Commercial gate operator service parts should be installed with power safely disconnected and the operator secured against movement. For high-voltage wiring, moving gate hazards, or uncertain field conditions, use a qualified gate technician.
Do not bypass this fuse or replace it with a higher amp fuse. Doing so can damage the operator and create an electrical safety hazard.
A slow-blow fuse can tolerate a brief startup surge but will open when there is a sustained overcurrent condition.
Some supplier references list 2500-1742 for OSCO SWD gate operators. Verify the exact operator wiring diagram before ordering.
Only use the fuse type specified by the operator documentation. A fast-acting fuse may nuisance blow, while the wrong slow-blow fuse can reduce protection.
That usually points to a circuit fault, damaged wiring, failed accessory, or other electrical problem that should be diagnosed by a qualified technician.
No. Do not increase the fuse rating. Use the specified rating and correct the underlying problem.
