Bussmann FNQ-R-7-1/2 CLASS CC TIME DELAY

Description

Features

• Designed with a specialized rejection tip, this Class CC fuse is engineered to fit into modern, high-interrupting-capacity fuse holders while preventing the dangerous installation of lower-rated fuses. This mechanical safety feature ensures your branch circuit remains fully code-compliant and protected against high-energy faults in industrial control panels.
• The FNQ-R-7-1/2 features a precision-engineered time-delay characteristic specifically tuned for the high inrush currents of small control transformers and motors. By providing a 12-second minimum opening time at 200% of its 7.5-amp rating, it eliminates frustrating system shutdowns during startup cycles while maintaining lightning-fast response to genuine short circuits.
• Rated to safely clear faults up to 200,000 Amps at 600V AC, this current-limiting fuse provides superior protection for sensitive downstream components. Its ability to rapidly restrict peak let-through current prevents catastrophic thermal and magnetic damage to your electrical infrastructure, ensuring maximum equipment uptime in demanding manufacturing settings.
• Built with a high-grade melamine tube and nickel-plated brass endcaps, this fuse offers exceptional physical strength and thermal stability in high-temperature environments. This rugged construction prevents the housing from becoming brittle or failing under stress, providing a reliable, maintenance-free overcurrent solution for your critical automation and HVAC control circuits.
