Special features
Rejection style
Feature: Current-limiting fast-acting fuse with a 5 A rating. Business impact: Reduces fault energy and arc-flash risk, enabling safer maintenance windows and protecting sensitive components. Application: HVAC control circuits and small-motor protection within panelboards. Feature: Rejection-style design for correct installation in fusible branch assemblies. Business impact: Minimizes installation errors and mis-mates, cutting project rework and downtime. Application: Commercial electrical panels and replacement programs in mixed-volt environments. Feature: High interrupt ratings of 100 kAIC at 600 Vac and 10 kAIC at 170 Vdc. Business impact: Robust protection for high-energy faults; supports reliable system uptime in critical processes. Application: Industrial power distribution, HVAC substations, and energy-intensive equipment. Feature: Class G, non-indicating, bulk packaging. Business impact: Clear protection class compliance with simple inventory management, reducing procurement time. Application: Large site rollouts and maintenance contracts with standardized spares. Feature: 600 Vac / 170 Vdc voltage rating with a compact footprint (1.31 in L Ă— 0.41 in W Ă— 0.41 in H). Business impact: Space-efficient protection in crowded panels and enclosures; easy to stock in bulk with minimal footprint. Application: Space-constrained electrical cabinets and retrofit projects. Feature: RoHS compliance and Bussmann-series compatibility. Business impact: Regulatory alignment and seamless integration with Eaton protection ecosystems; lowers lifecycle costs through standardization. Application: Regulatory-conscious installations and multi-brand protection schemes.
