JJS-100~TRON FAST ACTING FUSE CLASS T
Feature: Current-limiting protection reduces arcing and damage during faults → Business Impact: Minimizes equipment downtime and extends component life, enabling higher uptime in automation lines and packaging systems. Application: Ideal for VFD-driven conveyors and hopper systems where quick fault isolation is critical. Feature: 100 A amperage rating with 200 kAIC interrupt rating at 600 V → Business Impact: Provides strong short‑circuit protection without nuisance trips, improving system reliability and safety margins in harsh industrial environments. Application: Suitable for motor controls and drives in process automation. Feature: Small footprint and bolted blade end x bolted blade end connections → Business Impact: Easier installation in crowded control cabinets, reduces panel depth, and simplifies field servicing. Application: Replacement in retrofit projects and new builds where space is at a premium. Feature: Class T fast-acting design with TRON fast-acting characteristics → Business Impact: Fast fault clearance protects wiring insulation and downstream devices, lowering maintenance costs and extending cable life. Application: Critical for sensitive control circuits and high inrush loads common to modern manufacturing lines. Feature: Standard packaging (5 per box) and non-indicating operation → Business Impact: Streamlines procurement and stock management, while non-indicating design minimizes visual clutter in control panels. Application: General-purpose protection in switchgear assemblies and industrial automation panels. Feature: Compliance and documentation (CE Marked, RoHS Compliant) → Business Impact: Simplifies regulatory compliance audits and supplier qualification for global projects. Application: Global deployments requiring RoHS and CE compliance across automation assets.
