Eaton Specification Sheet - JM60100-1MW14
70–100 A amperage rating and 200 kA short-circuit rating provide robust protection for high-energy loads, reducing the likelihood of costly equipment damage and unplanned downtime. The Class J construction is optimized for branch circuit protection in industrial panels and motor control centers, delivering dependable coordination with downstream devices. The modular fuse block design simplifies replacement and modernization of protection schemes, allowing engineers to scale protection without rewiring. Lineside and loadside terminals are configured for straightforward wiring with common conductor sizes, which reduces installation time and potential miswiring during maintenance. The compact footprint—5.37 in long, 3 in high, 1.98 in wide—and light weight (0.33 lb) enable easier integration into crowded control panels and MCCs. Compliance with RoHS and CE Marking, along with UL Listed and CSA Certified status, supports regulatory acceptance in global facilities. Compatibility with Eaton Bussmann JM series enables standardized spares, faster deployment, and improved lifecycle planning for machine protection in manufacturing environments.

FAQs
JM60100-1MW14 is a single-pole modular fuse block designed for Bussmann JM systems. It features lineside terminals for 1/0–14 Cu/Al conductors and loadside terminals for 4–14 Cu, 4–8 Al, and 8–14 Cu conductors, enabling straightforward field installation in existing Eaton panels. Its compact 5.37 in length and 3 in height help preserve panel space, while UL Listed and CSA Certified ratings ensure compatibility with common industrial safety standards.
The fuse block is rated for 70–100 A with a short-circuit withstand of 200 kA and a voltage rating of 600 V. It is classified as Class J protection, UL Listed, and CSA Certified, with RoHS compliance and CE marking. These ratings support reliable protection for branch circuits in industrial equipment and help meet regulatory requirements for machinery protection.
This JM modular fuse block is commonly employed in panelboards, motor control centers, and machine controllers within manufacturing facilities. Its 600 V Class J protection and 200 kAIC fault tolerance make it suitable for protecting motors, drives, and associated control circuits, while its modular design supports scalable protection schemes across multiple machines and line-ups.
Class J fuse blocks offer fast-acting protection with reliable interrupting ratings suitable for low-impedance, high-current circuits typical in motor and drive applications. For 600 V systems, Class J provides a balanced combination of selectivity and protection, reducing nuisance trips while preserving equipment life. The JM60100-1MW14 leverages this class with a robust 70–100 A range and a 200 kAIC rating.
With a modular design and standardized JM series compatibility, maintenance operability improves through easier bumper-to-bumper replacement and reduced panel downtime. The 200 kAIC rating enhances fault tolerance, lowering the risk of catastrophic failures, while UL CSA RoHS CE compliance streamlines regulatory audits. Standardized spares and reduced wiring complexity translate to lower lifecycle costs and faster repair times.
