Eaton MIC-20 Fuse - 10 kAIC at 32V, Ferrule end
Part Number: MIC-20
Quick Summary
The Eaton MIC-20 fuse provides fast-acting protection for control circuits and PLC wiring in industrial panels. This compact midget fuse helps prevent nuisance trips while preserving essential electronics during surges. In practice, selecting a fuse with the right interrupt capacity and voltage rating is critical to avoid over-tripping or under-protection. While product data for this variant lists Not Applicable for warranty and compliances, MIC fuses are designed for low-voltage control environments and are compatible with ferrule-end terminations. When integrating into a panel, consider your plant’s safety standards and perform proper verification against CE/UL-style requirements. Using this fuse can improve system reliability and reduce downtime, while keeping initial costs manageable.

Eaton Specification Sheet - MIC-20
Feature → Business Impact → Application: The MIC-20 delivers fast-acting protection with a 20 A rating and a 10 kAIC interrupt capacity at 32 V, ensuring rapid fault interruption for control circuits and PLC wiring, which reduces fault energy and downtime in critical automation panels. This translates to improved reliability in ladder logic, remote I/O, and electronic control loops, especially in environments with transient overcurrents; ideal for compact control cabinets where space is at a premium. The ferrule-end x ferrule-end connection and nickel-plated bronze endcaps deliver durable, vibration-tolerant terminations that simplify installation and maintenance in industrial systems, while supporting quick fuse replacement without specialized tools. The MIC-20’s non-indicating design minimizes visual distractions inside enclosures, enabling straightforward inspection and scan-based fault tracing. Its standard packaging and 0.47 in length/width, 1.813 in height form-factor fit common fuse holders and panel layouts, reducing redesign costs during retrofits. In practice, engineers can source a compatible, high-reliability component that integrates with control circuits, PLC inputs/outputs, and electronic circuits with predictable performance under repeated surge events.

FAQs
The MIC-20 uses ferrule-end x ferrule-end connections and a compact 0.47 in by 0.47 in cross-section with a height of 1.813 in, designed to fit standard fuse holders in control panels. This compatibility simplifies replacement in existing enclosures and minimizes the need for adapter parts. Ensure your panel supports ferrule-terminals and that the holder spacing matches the fuse’s dimensions for reliable seating and hold-down.
MIC-20 provides a 10 kAIC interrupt rating at 32 V, meaning it can safely interrupt fault currents up to 10 kiloampere at a 32-volt level. This rating is suitable for safeguarding control circuits, PLC wiring, and electronic circuitry from short-circuit events typical in industrial environments, helping prevent equipment damage and cascading failures.
Yes. The MIC-20 is designed for fast-acting protection in control circuits and PLC wiring, offering a 20 A rating at 32 V with a ferrule-end connection. Its small, non-indicating form factor minimizes enclosure clutter while providing reliable overcurrent protection, making it well-suited for PLC inputs/outputs and other electronic control applications in automation systems.
The product data for MIC-20 lists warranty and compliances as Not Applicable. When selecting for regulated environments, verify regional or site-specific approvals via Eaton’s official spec sheets or regional catalogs. For reference, consult the Eaton MIC-20 datasheet and ensure your installation adheres to local electrical safety standards and panel-certification requirements.
Install MIC-20 in a properly rated fuse holder with ferrule-terminals, using standard packaging to simplify stocking and replacement. Maintain enclosure cleanliness, ensure correct seating to prevent arcing, and replace after a fault event to restore protection. The 32 V rating and 20 A capacity support typical control-panel duty while keeping costs predictable and downtime low in routine maintenance.
