Bussmann series Fuseology
80 A amperage rating paired with high interrupt ratings provides strong fault-clearing capability, minimizing equipment damage and reducing downtime in control panels. Business Impact: improved equipment availability and lower maintenance costs. Application: control circuits in machine automation, where dependable protection against short circuits is essential. The time-delay, dual-element design tolerates inrush currents common to motor starters, preventing nuisance trips while preserving safety margins. This translates to smoother operation of conveyors and presses, and a shorter MTTR for panel faults. The current-limiting feature helps confine fault energy, enabling safer maintenance and extended component life in distribution blocks. Application context includes power distribution in compact electrical cabinets and panel boards. The compact footprint and blade-end connections simplify retrofit projects and new installations in space-constrained architectures. The electrically isolated end caps improve field service safety and reduce potential cross-talk in dense panel layouts. Packaging of five pieces per pack supports efficiency in procurement and stocking for maintenance teams. Compliance with CE and RoHS ensures regulatory alignment for global installations and traceable material provenance.
