Eaton Specification Sheet - JM60400-2MW16
Feature → Business Impact → Application: The JM60400-2MW16 delivers high-current, two-pole Class J protection for industrial power panels, enabling robust overcurrent protection with a 200 kAIC rating. This translates to fewer nuisance trips and enhanced equipment uptime in demanding environments such as packaging lines and motor control centers. Application-wise, the device supports lineside connections up to 600MCM and 4 AWG Cu/Al and loadside terminals from 2–14 AWG Cu and 2–8 AWG Al, simplifying field wiring and reducing installation time in machine enclosures. Another benefit is RoHS compliance and CE marking, ensuring compliance across global supply chains and facilitating cross-border manufacturing. Compatibility with the Eaton Bussmann JM family means faster integration, standardized maintenance, and predictable spare-part stocking. The modular design also helps address downtime-related objections by enabling rapid fuse replacement without extensive rewiring, improving overall total cost of ownership.
