Bussmann FNQ-R-6 Current-limiting Time-delay Fuse 6 A, 600 V, 200 kAIC, Melamine Tube

Description

Features

• Engineered specifically to handle intense inductive inrush currents, the FNQ-R-6 features a built-in 12-second time-delay at 200% load. This specialized calibration prevents frustrating, premature nuisance tripping caused by small control transformers and industrial motors, keeping your automated production lines and control panels continuously operational.
• As an advanced LIMITRON™ protection device, it offers up to 10X better current limitation compared to standard supplemental fuses, rapidly choking off massive fault currents before they can devastate your downstream electronics. This high-performance protection minimizes localized arc-flash energy, shielding expensive PLC modules and control circuits from catastrophic thermal or magnetic damage.
• Designed with a strict physical rejection tip, this 13/32" x 1-1/2" cartridge fuse is mechanically keyed to seat perfectly into dedicated Class CC rejection-style blocks and DIN-rail holders. This mechanical safety barrier guarantees maintenance personnel cannot mistakenly install a lesser-rated supplementary fuse, enforcing strict compliance with NEC® and UL branch-circuit hardware mandates.
• Boasting an exceptional 200,000 AIC rating at 600Vac, this fuse safely clears heavy short-circuit faults on massive industrial power grids without violently rupturing. This extreme interrupting capability ensures your control panels easily fulfill strict OSHA and NEC® Section 110.9 safety guidelines for high-capacity branch circuit environments.
