Eaton Specification Sheet - JM60400-2MW26
High current protection with a 225-400 A amperage rating and a 200 kA short-circuit rating, at a 600 V rating, delivers robust defense against fault conditions and minimizes downtime in critical power circuits. This translates to measurable uptime gains and lower maintenance costs in manufacturing lines and safety-critical applications. The JM60400-2MW26 utilizes a two-pole Class J configuration with defined lineside terminals (2) of 350 kcmil - 6 AWG Cu/Al and loadside terminals (6) of 2 - 14 AWG Cu and 2-8 AWG Al, simplifying wiring, reducing install time, and enabling flexible integration in control panels and motor control centers. The modular fuse block design supports scalable channel count and straightforward field upgrades, reducing panel rework and inventory complexity. Compliance with RoHS and CE marks ensures global deployment without redesign, while UL Listed and CSA Certified ratings provide regulatory assurance for cross-border manufacturing and equipment reliability. Industry-specific insight shows these features align with lean manufacturing goals, OT security, and safe energy distribution, especially in machine builders and system integrators.
