FNQ-R-17-1/2 TIME DELAY FUSE

Product Description

The FNQ-R-17-1/2 Time Delay Fuse is a Class CC, dual-element, current-limiting fuse designed for protecting control circuits, transformers, and industrial electrical systems where temporary inrush current is expected.

It is part of the Eaton Bussmann FNQ-R “CC-Tron” series and is widely used in control panels, PLC circuits, HVAC systems, and small motor/transformer protection.

Key Features

• Time-delay (slow-blow) fuse for handling inrush currents
• Class CC rejection-type fuse for secure compatibility
• Dual-element design for better overload + short-circuit protection
• High current-limiting capability for equipment safety
• Withstands temporary motor and transformer start surges
• Compact cylindrical cartridge design
• Very high interrupting rating for industrial protection
• Fits standard Class CC fuse holders (rejection type)
• Reliable protection for sensitive control systems
• Industrial-grade construction for long service life
