Bussmann series Fuseology
Eaton Specification Sheet - JM60400-1MW22
High current capability and a high short-circuit rating translate into meaningful uptime protection for main feeders in power distribution panels. The 225-400 A range paired with 200 kA short-circuit rating minimizes the risk of cascading faults, delivering faster fault isolation and reduced downtime in manufacturing lines and process facilities. This fuse block accommodates large conductors, enabling clean, fewer-splice installations for improved reliability. Its compact 7.9 in length, 4.79 in height, and 3.53 in width support easier panel integration and faster commissioning, reducing assembly time and space constraints. Built to Class J standards and single-pole configuration, it delivers dependable operation with standard Bussmann series interfaces, simplifying replacement and maintenance. RoHS and CE markings, along with UL Listed and CSA Certified status, streamline procurement and compliance across international sites, lowering sourcing risk and total cost of ownership. The unit’s heavy-duty construction and specified wiring harnesses help reduce panel temperatures and improve fault-clearance times in demanding environments, contributing to safer and more efficient electrical protection schemes.

FAQs
The JM60400-1MW22 supports two conductor configurations: (2) 350 kcmil-1 AWG and (2) 2 AWG-6 AWG. This enables large feeder connections and flexible field wiring, reducing the need for intermediate splices. When planning installation, ensure conductor sizes match the single-pole Class J design and maintain appropriate torque on terminations per manufacturer guidelines.
The fuse block provides a 200 kA short-circuit rating and a voltage rating of 600 V. These ratings support robust protection for industrial power distribution panels and large feeders, helping to prevent damaging fault currents from propagating through the system while enabling reliable operation in medium- to high-power applications.
Yes. With a 225-400 A amperage range, 600 V maximum voltage, and class J single-pole construction, the JM60400-1MW22 is designed for power feeds to industrial machinery and control cabinets. Its RoHS/CE/UL CSA certifications also streamline integration into safety-critical panels and ensure compliance across global facilities.
The JM60400-1MW22 carries UL Listed and CSA Certified marks, along with CE marking and RoHS compliance. These certifications confirm safety, regulatory alignment, and environmental compliance for machinery and panel builders, reducing procurement risk and simplifying audits for international deployments.
The modular fuse block reduces maintenance overhead by supporting straightforward wiring for large conductors and providing clear fault paths, which speeds fault isolation. Its durable Class J construction and wide amperage range help minimize unplanned downtime, improving equipment availability and lowering total cost of ownership for systems with high current protection needs.
