Eaton JM60400-3MW22 Modular Fuse Block - Class J

High amperage and fault protection: The JM60400-3MW22 is rated for 225-400 A with a 200 kA short-circuit rating at 600 V, delivered in a rugged three-pole Class J configuration. This minimizes unplanned outages by clearing faults quickly and keeping feeders energized during routine load changes. Application: Well-suited for motor drives, machine control panels, and packaging lines that demand dependable protection with a compact footprint. Wire-size versatility and termination efficiency: It accommodates two large feeders and two smaller conductors: (2) 350 kcmil-1 AWG and (2) 2 AWG-6 AWG, enabling engineers to consolidate power distribution in a single modular block. This reduces hardware variety and installation time while maintaining code-compliant termination and vibration resistance in harsh environments. Compliance and lifecycle reliability: RoHS Compliant and CE Marked, with UL Listed and CSA Certified labeling, giving teams confidence in meeting global electrical-safety requirements. The Class J rating plus RoHS and CE compliance support safer panels, streamlined procurement, and easier post-install audits. Installation and compatibility: As part of the Eaton Bussmann series, this JM modular fuse block integrates with existing Bussmann fuses and accessories for consistent performance and spare parts availability. Its compact, lightweight design simplifies panel layouts, reduces wiring errors, and enables faster field modifications during expansion projects. Field performance insights: Operators report smoother maintenance cycles and lower inventory costs thanks to a standardized 600 V, three-pole solution with clear conductor sizing and documented ratings. With a broad Bussmann ecosystem, sourcing and replacements are predictable and quick.
