140CFU08000
Schneider Electric
Overview
The Schneider Electric 140CFU08000 is a fuse kit designed for the Modicon Quantum series, providing replacement fuses that protect Quantum modules and circuits against over-current conditions. It is a consumable accessory rather than a logic or I/O module, and it is specified with a rated current of 0.8 A and a voltage rating of 250 V, handling a maximum current of 630 mA.
The kit is intended for integration within Quantum systems where a fuse of these ratings is called up by the module design. It is rated for an ambient temperature range of 0 to 40 °C and a maximum operating humidity of 80 % non-condensing, with a maximum operating altitude of 1000 m without derating. Keeping genuine fuses on hand avoids improvised replacements that could compromise protection.
Application & Technical Notes
The 140CFU08000 is a support accessory, not a programmable module, so its role is protective rather than functional. The 0.8 A rated current and 250 V voltage rating define the circuit conditions it is designed to protect; using fuses of the wrong rating defeats the protection and may damage the module or violate approvals.
Integration is simply a matter of installing the correct fuse in the designated Quantum holder or module as described in the equipment documentation. Because the ambient limit is 0–40 °C and humidity is capped at 80 %, ensure the enclosure environment is suitable for the kit's storage and any accessible location.
Maintenance & Diagnostics
As a fuse kit, maintenance is essentially replacement when a fuse has opened due to an over-current event. Always identify and correct the underlying fault before fitting a new fuse, since repeated blowing indicates a field-side or module problem. Keep spares in a dry location within the rated storage range and avoid exposing the kit to condensation.
Do not bridge or up-rate fuses, as that removes the intended protection and can create a fire or equipment-damage hazard. During panel work, follow lockout/tagout practice and verify the circuit is de-energised before replacing a fuse.
Sourcing & Procurement
The 140CFU08000 is a genuine Schneider Electric fuse kit; for protection integrity it is best to use the specified genuine fuses rather than generic substitutes of unknown rating and certification. Confirm the 0.8 A / 250 V rating matches the circuit called up by your Quantum module.
Genuine kits are recommended because protection performance and approvals depend on the authentic part. For ongoing operations, hold a small stock of genuine fuses sized to your installed base. Buy from authorised distributors where possible and retain the manufacturer part number for reordering.
Frequently Asked Questions
What is the 140CFU08000?
It is a fuse kit (consumable accessory) for the Modicon Quantum series, not a logic or I/O module.
What are its ratings?
Rated current 0.8 A, voltage rating 250 V, with a maximum current handling of 630 mA.
What environment is it rated for?
Ambient temperature 0 to 40 °C and maximum operating humidity 80 % non-condensing, up to 1000 m altitude without derating.
Can I use a generic fuse instead?
It is best to use the specified genuine fuse; wrong ratings defeat protection and may damage the module or void approvals.
What should I do if a fuse blows?
Find and fix the underlying over-current fault before fitting a new genuine fuse; never bridge or up-rate the fuse.
