Eaton FNQ Series Cartridge Fuse, 2.5A Current Rating, 500V AC Voltage - FNQ-2-1-2

This cartridge fuse provides time-delayed overcurrent protection for industrial electrical systems, designed to interrupt fault currents while tolerating short-term surges. It is intended for use in control panels, distribution assemblies and equipment where a slow-acting protective device is required to prevent nuisance openings during start-up or transient conditions.

Features and Benefits:

• Time-delay element reduces nuisance trips during inrush events
• T-speed classification delivers consistent slow-blow behaviour
• 2.5A rating limits sustained overcurrent to protect circuits
• 500V AC capability supports high-voltage industrial installations
• Fibre body offers electrical insulation and thermal stability

Applications

• Suitable for motor starter control circuits with high inrush
• Ideal for protection of transformers and power supplies
• Used with automation PLC input power lines
• Can be used for protection in electrical distribution panels

What is the allowable current handling characteristic under transient conditions?

The fuse is designed with a time-delay characteristic that permits short-duration surge currents above its 2.5A steady-state rating without opening, enabling equipment start-up currents to pass briefly.

What electrical stress levels can it withstand during normal operation?

It is rated for operation on AC systems up to 500V, making it suitable for many industrial low-voltage distribution networks.

How does the construction influence installation safety?

The fibre-bodied construction provides dielectric insulation around the fuse element, reducing the risk of conductive tracking within fuse-holders while maintaining thermal endurance.

What type of speed characteristic should engineers expect when selecting this device?

The device follows a T-speed slow-blow characteristic, offering delayed clearing times compared with fast-acting devices to address inrush and transient events without immediate interruption.
