FAQs
NOS-225 is a Bussmann series Class H non-current-limiting fuse, designed to fit standard Bussmann holder assemblies. Always verify holder compatibility in the Eaton Bussmann catalog and match for the 600 V system and 225 A rating to ensure proper installation and fault clearance performance.
NOS-225 provides a 225 A amperage rating with a 10 kAIC interrupt rating at 600 VAC and a voltage rating of 600 V. These specs enable robust protection for medium to large feeders and MCCs, allowing safe interruption of short-circuit currents while minimizing downstream equipment damage.
Yes. Its Class H, non-current-limiting design paired with a 10 kAIC interrupt rating at 600 VAC makes it appropriate for motor feeders and MCC sections where predictable fuse behavior and reliable interruption are critical for equipment protection and uptime.
NOS-225 is CE marked, indicating conformity with European safety standards. RoHS compliance can be verified via Eaton’s RoHS tools and catalogs, supporting regulatory alignment for global deployments and eco-friendly material usage in line with regional requirements.
As a one-time NOS fuse, NOS-225 reduces maintenance intervals by delivering reliable protection without back-up current-limiting behavior. Its clear 225 A rating and pin-indicating features speed installation checks, lowering field downtime and improving overall panel uptime and return on investment.
