Fast-acting response delivers precise interruption at 3 A to protect delicate control electronics and PLC inputs. This reduces arc energy and limits damage to relays, timers, and sensors during fault events. In high-density panels, fast protection translates into shorter outage durations and safer startup sequences. The 100 AIC interrupt rating at 250 Vac provides robust short-circuit protection for control feeds and cross-connection points. It tolerates short surges without tripping on transient anomalies, while still delivering reliable shutoff during true faults. This balance minimizes nuisance trips and extends component life. Ferrule end x ferrule end connections enable secure, repeatable terminations with standard ferrules and copper conductors. The availability of ferrule terminals speeds up installation in crowded control cabinets and simplifies field replacement. Compatibility with common Bussmann MIC-series wiring schemes reduces training time for technicians. Nickel-plated bronze endcaps and a fiber tube resist corrosion and wear in vibration-prone environments. The rugged construction supports long service life in conveyors, packaging lines, and process automation. These internal features also help maintain conductivity under thermal cycling. Non-indicating design reduces panel noise and visual clutter, making fault diagnostics quicker. The compact 1.813 in length and 0.47 in width fit standard enclosures without crowding nearby feeds. Standard packaging further simplifies stocking and reorder processes. CE Marked compliance ensures alignment with European safety directives and supports regulatory readiness for machine builders and end users. The MIC-3 integrates smoothly into standard control-system protection strategies for PLCs, timers, and logic modules, delivering consistent performance in industrial automation. Overall, the MIC-3’s combination of protection, durability, and ease of procurement translates to measurable uptime gains and lower maintenance costs.

FAQs
MIC-3 uses ferrule end terminations, compatible with standard ferrule cables and common Bussmann MIC-series wiring schemes. Its compact 1.813 in length and 0.47 in width fit tight panel spaces, while the non-indicating design reduces front-panel clutter. Ensure the amperage rating (3 A) and voltage rating (250 V) match your control circuit requirements before installation.
The 100 AIC (AMPS Interrupting Capacity) rating indicates the fuse can safely interrupt short-circuit currents up to 100 amperes without failing, protecting connected devices. In practice, it means robust fault protection for small control feeds while preventing unnecessary interruptions from minor transients, supporting reliable PLC operation and reduced downtime.
Yes. MIC-3 is designed for control circuits and PLC protection, offering fast-acting interruption at 3 A and a 250 V rating. Its ferrule-end connections and durable nickel-plated endcaps suit industrial environments, while CE Marked compliance helps ensure regulatory alignment for European installations.
MIC-3 carries CE Marked compliance, indicating conformity with European safety standards. While other certifications are not listed in the provided data, the CE Mark signals suitability for European machinery and panel installations. Always verify current Eaton documentation for any updates on additional certifications.
Using MIC-3 can lower downtime by preventing fuse-related faults and simplifying replacement with a standardized, small footprint. Its durable construction minimizes wear in vibration-prone equipment, while the non-indicating design reduces inspection time. Over the equipment lifecycle, this translates into lower maintenance costs and improved return on investment for automation projects.
