Eaton
Part number
JKS-225

Quick Summary

The Eaton JKS-225 fuse provides fast-acting overcurrent protection for low-voltage distribution in industrial panels and machinery. Choosing the wrong fuse can cause nuisance trips, downtime, and costly equipment damage during startup and routine maintenance. RoHS compliance, Class J fast-acting design, and a 200 kAIC interrupt rating at 600 V help you meet safety, reliability, and lifecycle goals. Standardizing on the JKS-225 gives engineers predictable performance, easier procurement, and clearer specifications for sourcing teams. This makes it a compelling choice for electrical protection and circuit control in automation projects where uptime matters.

Feature — The JKS-225 delivers fast-acting Class J protection with current-limiting behavior to rapidly isolate fault conditions. Business impact — This reduces conductor insulation stress, minimizes arc energy, and lowers the risk of collateral damage during fault events. Application — Ideal for LV power distribution, motor drives, and control panels in automation environments where uptime matters. Feature — Amperage rating of 225 A and voltage rating of 600 V with a 200 kAIC interrupt capacity. Business impact — Provides reliable margin against high fault currents in modern switchgear, improving safety margins and protecting feeders and devices. Application — Suitable for medium-to-large loads in MCCs, feeders, and industrial control circuits across process automation. Feature — Rejection-style end connections prevent incorrect fuse insertion during routine maintenance or panel upgrades. Business impact — Reduces field wiring errors, simplifies stocking, and speeds replacements in critical downtime windows. Application — Valuable in retrofit projects and multi-vendor assemblies where installation accuracy matters. Feature — Bolted blade end x bolted blade end design offers robust, vibration-resistant mounting in harsh industrial environments. Business impact — Ensures reliable contact resistance, lowers wear on contact surfaces, and extends service intervals for critical circuits. Application — Suitable for switchgear, LV distribution blocks, and machine panels with vibration and temperature variation. Feature — RoHS-compliant construction aligns with global material restrictions and sustainability goals. Business impact — Streamlines regulatory audits, simplifies cross-border procurement, and reduces waste management complexity. Application — Supports global automation deployments and multi-site spare-parts strategies for electrical protection.

FAQs

To install the JKS-225, align the bolted blade ends with the corresponding panel bus bars, tighten to the manufacturer’s torque specification, and verify proper seating to avoid loose contacts. Use the rejection-style end to prevent incorrect part insertion. Always de-energize the circuit and follow lockout/tagout procedures before replacing fuses, then confirm continuity after installation.
The JKS-225 combines fast-acting operation with current-limiting design typical of Class J fuses, enabling rapid interruption of faults. With a 225 A rating, 600 V rating, and 200 kAIC interrupt capacity, it clamps fault current and minimizes arc energy, protecting conductors and equipment while reducing downtime and collateral damage.
Yes. The 225 A, 600 V Class J fuse is well-suited for LV motor protection, feeders, and control panels in MCCs and switchgear. Its fast fault clearance and high interrupt rating make it a reliable choice for automation environments where motor drives and process equipment require dependable overcurrent protection with straightforward coordination.
The JKS-225 is RoHS compliant, aligning with global material restrictions and sustainability goals. While it adheres to standard Class J fuse specifications, confirm any site-specific regulatory requirements (such as CE or UL/CSA listings) with your procurement team to ensure full compliance for your region and application.
Because JKS-225 fuses are non-indicating and use a rejection-style end, maintenance and replacement are straightforward and quick, reducing downtime. Stock the same model and rating for rapid swap-out after a fault event, improving mean time to repair and overall lifecycle cost, while maintaining consistent protection across panels and machines.
