Problem: A Blown Fuse Stops the Whole Line
A single blown fuse in a Modicon Quantum rack can halt production. The 140CFU08000 from Schneider Electric is the practical answer: a fuse kit built specifically for the Modicon Quantum series. It carries a 0.8 A rated current and a 250 V voltage rating, with a maximum current of 630 mA. When your control cabinet needs a ready-to-ship spare, this is the part that keeps downtime short.
What the 140CFU08000 Fuse Kit Delivers
This is not a generic fuse. It belongs to the Modicon Quantum product line, so it fits the protection scheme the platform was designed around. The kit protects Quantum modules from overcurrent events while keeping the electrical profile predictable.

Why These Ratings Matter
The 0.8 A rated current and 630 mA current rating define the protection window. Fit the correct fuse and the module is shielded from surges; fit the wrong one and nuisance trips or unprotected faults follow. The 250 V rating covers the working voltage of the circuit. The 0 to 40 degrees Celsius ambient range suits typical control-room conditions, and 80% non-condensing humidity applies to both operation and storage, so spares kept on a shelf stay serviceable.
Where the 140CFU08000 Fits
Oil and Gas Control Rooms
Quantum racks run pumps, valves and safety interlocks across upstream and midstream sites. A fuse kit on the shelf means a fault gets cleared in minutes, not days. That is the ROI case: one spare prevents a full shift of lost output.
Industrial Automation Panels
System integrators building or servicing Quantum-based panels keep this kit in the spares bin. It matches the platform, so no cross-referencing or adapter hunting is needed.
High-Altitude and Humid Plants
With a 1000-meter altitude limit without derating and 80% non-condensing humidity tolerance, the kit suits plants in coastal or elevated regions where lesser components degrade faster.
Installation and Maintenance Pointers
Fuse replacement is a maintenance task, not a design change. Isolate the circuit, follow the panel’s lockout procedure, and confirm the replacement matches the original rating. Inspect fuses periodically as part of routine cabinet checks, and log any repeat failures, because a fuse that blows twice usually points to a deeper fault. Store spares in a dry, non-condensing environment within the stated humidity limit.
Please verify current lifecycle status and availability with Oil AutoTech before ordering.
Selection Checklist
Before you buy, confirm the product line is Modicon Quantum, the rated current is 0.8 A, and the voltage rating is 250 V. Check that your ambient conditions sit inside 0 to 40 degrees Celsius and 80% non-condensing humidity. If you are unsure which fuse kit suits your rack, ask for hands-on technical selection help.
