FAQs
Yes. The JM60400-2CR is a two-pole modular fuse block designed for use with the Bussmann JM series and Class J fuses. Its knife blade end connections simplify wiring and help ensure reliable mating within standard panel layouts. When upgrading, verify enclosure clearance and mounting provisions to maintain clearance for bus bars and thermal management.
Key ratings include amperage 225-400 A, voltage 600 V, interrupt rating 200 kAIC, and short-circuit rating 200 kA. These specs enable safe interruption of high‑fault currents, protect downstream equipment, and support reliable operation in demanding industrial environments such as motor drives and feeders in control panels.
The JM60400-2CR is well suited for electrical distribution panels, motor control centers, and machine feeders in manufacturing, processing, and automation environments. Its two-pole Class J design and high current capability make it ideal for high‑demand applications where space is constrained and service life matters, such as conveyors, pumps, and presses.
The fuse block carries UL Listed and CSA Certified marks, along with RoHS compliance and CE marking. This combination supports global market acceptance and simplifies regulatory approvals for panels shipped to North America and Europe, while ensuring environmental compliance and safer materials within electrical assemblies.
The modular design with knife blade ends reduces wiring effort and accelerates fuse replacement, cutting maintenance time and labor costs. The high interrupt rating lowers the risk of costly outages, while UL/CSA compliance supports fewer rework steps during audits. Overall, customers see improved uptime, simpler spares management, and faster deployment in new builds or retrofits.
