Eaton FNQ-R Series Cartridge Fuse, 12A Current Rating, 600V AC Voltage - FNQ-R-12

This cartridge fuse provides time-delayed overcurrent protection for electrical systems where temporary inrush currents occur. It is designed for AC circuits up to 600V and accommodates applications requiring slow-response interruption to protect components without nuisance blowing. The device employs a fibreglass body and is intended for installations needing standard 10x38mm fuse geometry.

Features and Benefits:

• Time-delay characteristic reduces false trips during motor start-up
• Rated current 12A to protect mid-range circuits
• T speed classification for slow-blow performance
• UL 248-14 recognition for standardised safety requirements
• Fibreglass construction for mechanical stability and insulation

Applications

• Suitable for safeguarding motor control circuits subject to inrush currents
• Ideal for protecting industrial automation equipment
• Used with control panels in electrical distribution systems
• Can be used for protection of electronic drive modules

What operating voltage can it handle in AC systems?

It is rated for operation up to 600V AC, making it suitable for common industrial supply voltages.

How does the slow-response behaviour affect circuit protection?

The time-delay response permits short-duration current spikes to pass while interrupting sustained overloads, reducing unnecessary interruptions during transient events.

What physical form factor should installers expect?

The component conforms to a 10x38mm cartridge format with an overall length of 38mm and a Compact 10mm diameter for panel and holder compatibility.

What material provides the fuse body’s insulation and strength?

The body is manufactured from fibreglass to offer electrical insulation and structural integrity in typical industrial environments.
