Fluke 315 mA Fuse, 1 Piece

A. Product Overview

The Fluke 315mA 1000V Fuse is a professional-grade safety fuse designed for Fluke testing instruments and insulation resistance testers. It is engineered to provide dependable protection during electrical measurements by limiting fault energy and preventing damage to sensitive internal components.

This high-energy fuse features a fast-release design and sand-filled construction that helps absorb shock energy generated during current overload conditions. It is designed to protect users from electrical hazards such as electric shock, burns and potential fire risks during short-circuit events.

Product Details:

• Product Name: Fluke 315mA 1000V Fuse
• Part Number: 2279339
• Fuse Rating: 315mA, 1000V
• Type: High-energy fast-release fuse
• Construction: Sand-filled ceramic fuse

B. Working Principle

A fuse works by interrupting the electrical circuit when current exceeds the safe operating limit.

The Fluke 315mA 1000V Fuse contains a calibrated fuse element that melts when excessive current flows through the circuit. This disconnects the electrical path and prevents further current flow, protecting the measuring instrument and the user.

The sand-filled design absorbs the energy generated during overload conditions. The sand helps reduce the risk of fuse damage by absorbing high temperatures and limiting oxygen availability, which helps suppress potential combustion during high-energy faults.

Frequently Asked Questions (FAQ)

1. What is the Fluke 315mA 1000V Fuse used for?

The Fluke 315mA 1000V Fuse is used as a replacement safety fuse for compatible Fluke insulation testers and electrical measurement instruments to provide protection against overloads and short circuits.

2. What is the rating of this Fluke fuse?

This fuse is rated at 315mA and 1000V.

3. What is the part number of the Fluke 315mA fuse?

The part number of this fuse is 2279339.

4. Why is this fuse sand-filled?

The sand-filled construction helps absorb overload energy and high temperatures generated during fault conditions, improving safety and reducing the risk of fire or fuse breakage.

5. Which Fluke instruments use this fuse?

This fuse is designed for compatible Fluke insulation testers and electrical measurement instruments, including models such as Fluke 1503 and Fluke 1507 insulation testers.

6. When should the Fluke fuse be replaced?

The fuse should be replaced when the instrument stops performing current measurements correctly or when the existing fuse has operated due to an overload or fault condition.

7. Can a normal fuse be used instead of a Fluke 315mA 1000V Fuse?

No. Using the correct Fluke-rated fuse is recommended because it is specifically designed to handle the safety requirements and fault energy levels of Fluke testing instruments.

8. Who should keep spare Fluke 315mA fuses?

Professionals who regularly perform electrical testing, insulation resistance testing and industrial maintenance should keep spare fuses to avoid downtime during field operations.
