Eaton Specification Sheet - JM70100-1CR
The modular design of the JM70100-1CR fuse block enables a compact footprint that reduces cabinet depth and simplifies panel layouts, accelerating assembly and wiring in control panels. This translates to faster commissioning and lower labor costs, while maintaining robust Class J protection for critical circuits. With a 200 kAIC interrupt rating, it absorbs short-circuit energy more effectively, reducing arcing damage and downtime in heavy machinery applications. The 700 V voltage rating expands its applicability to a wider range of control circuits, improving system flexibility and future-proofing panel designs. Box lug terminations provide secure, field-friendly wiring connections that resist vibration and torque, improving reliability in harsh environments. Compliance attributes—UL Listed, CSA Certified, RoHS, and CE Mark—minimize regulatory risk and streamline procurement across global facilities. The product’s compatibility with Eaton Bussmann series tooling and datasheets supports faster sourcing and consistent spare-part strategies.

FAQs
The JM70100-1CR is a modular fuse block from Eaton’s Bussmann series, rated at 100 A with Class J protection, 700 V, and 200 kAIC. It is typically used in control panels for industrial machinery, process equipment, and safety circuits where compact form factor and high short-circuit energy handling are required. It integrates with box-lug terminations for reliable field wiring and is UL Listed and CSA Certified for broad regulatory acceptance.
Yes, the JM70100-1CR is designed for Class J fuses and uses a box lug connection for single-pole configurations. When wiring, ensure proper conductor sizing for 100 A ratings, secure torque on lug terminals to minimize resistance, and follow applicable NEC/IEC guidelines. The 700 V rating supports control circuits in industrial panels, while the 200 kAIC interrupt rating provides robust short-circuit protection for high-energy faults.
The JM70100-1CR carries UL Listed and CSA Certified markings, is RoHS compliant, and CE marked. These certifications confirm adherence to safety, environmental, and international regulations, facilitating global procurement and reducing compliance burdens for multinational facilities.
Key considerations include using box lug terminations designed for secure field wiring, maintaining proper clearance within the panel, and ensuring conductor insulation and gauge match the 100 A rating. The device’s 200 kAIC interrupt capability helps handle high-energy faults, so verify panel short-circuit ratings and enclosure protection (RoHS/CE compliance). Regular inspection of lug torque and mounting integrity supports long-term reliability.
The JM70100-1CR offers quick field replacement and standardized components from the Bussmann series, reducing downtime during fuse changes and spares stocking complexity. Its compact, modular design lowers panel footprint and wiring complexity, supporting faster commissioning and ongoing maintenance. Combined with UL/CSA approvals and RoHS CE compliance, it minimizes regulatory risks while delivering dependable protection for machine-critical circuits.
