FAQs
The BK/JM60400-1CR is designed for use in panels that accept JM Bussmann modular fuse blocks and similar single-pole, high-current configurations. It integrates with standard Bussmann JM-series layouts, enabling quick swaps and consistent wiring schemes across industrial control panels, machine builds, and process equipment.
The 400 A rating provides robust protection for main distribution circuits and high-current loads. In practice, this limits fault current exposure to downstream components, reduces arc-flash risk, and minimizes the likelihood of cascading failures in demanding applications such as motor drives and high-capacity PLC cabinets.
Yes. The block is RoHS Compliant and carries UL Listing as well as CSA Certification, aligning with global regulatory expectations. These certifications support compliance across diverse markets and streamline acceptance in regulated industries like automotive, aerospace, and food processing.
Plan for bulk-pack CR blocks by ensuring you have compatible JM-series fuse bases and adequate space for the single-pole module. Verify conductor sizing and torque requirements per the manufacturer’s guidelines, and prepare for efficient stocking by leveraging the bulk-pack format to reduce replenishment cycles and procurement lead times.
Using a bulk-pack JM60400-1CR reduces stocking complexity and part-count variety, lowering carrying costs. Its compatibility with standard JM-series components simplifies preventive maintenance, speeds replacement, and minimizes downtime, delivering tangible ROI in high-volume manufacturing,OEM builds, and service contracts.
