Thermal Fuse 84°C (184°F) – VET8081 Axial Lead Thermal Cutoff

Reliable Overheat Protection with the VET8081 Thermal Fuse

The VET8081 thermal fuse from Vetco Electronics Semiconductors is a temperature-sensitive, non-resettable device designed for dependable circuit protection in appliances and electronic equipment. Rated to open at 84°C (184°F), this axial lead thermal cutoff fuse helps safeguard your devices by interrupting power if temperatures rise above a safe level.

Technical Details and Ratings

• Part Number: VET8081 (originally NTE8081)
• Functioning Temperature: 84°C (184°F)
• Holding Temperature: 60°C (140°F)
• Maximum Temperature: 125°C (257°F)
• Maximum Current Rating: 15A
• Voltage Ratings: 120/250 VAC, 15A (continuous 10A); 240 VAC, 25A RES (16.7A continuous); 277 VAC, 20A RES (15A continuous); 120–277 VAC, 125VA pilot duty; 180 VAC, 3A motor rating
• Lead Type: 18 gauge solid copper wire, 1 1/3” leads
• Compliance: UL listed (File No. E49429, E117626), CSA (File No. LR43279), and VDE (File No. 115369)

Typical opening temperature tolerance is +0°C, -5°C for added reliability. The electrical resistance is as low as a comparable length of 18 gauge copper, ensuring efficient current flow.

Ideal Applications for Home and Electronics

VET8081 thermal fuses are perfect for everyday electronics and household appliances where overheating could be a safety risk. Compatible with products such as hair dryers, refrigerators, irons, toasters, battery chargers, glue guns, coffee makers, dishwashers, fans, UPS backups, electric motors, and many more. The VET8081 fuse ensures your equipment automatically disconnects in response to excessive heat, providing peace of mind for your family and devices.

How the VET8081 Thermal Fuse Works

This thermal cutoff fuse features an internal organic pellet that changes phase at its rated temperature. When triggered, spring-activated contacts permanently open the circuit—protecting your appliance until the fuse is replaced. The VET8081 is non-resettable, so quick, affordable replacement is easy – no complicated resets required.

Features & Certifications

• Fully compliant with UL, CSA, and VDE standards for added assurance
• Miniature design fits almost any space or replacement configuration
• No crimp connectors included for a streamlined installation

Note: Temperature sensitive device—do not store above 48°C (120°F). Color band does not indicate temperature group.

With proper air flow, heat generation below 15 Amps is minimal. For continuous operation, a good rule of thumb is to use the fuse at least 30°C below its maximum opening temperature for long-term reliability.

Why Choose Vetco Electronics Semiconductors?

When NTE left the market, Vetco Electronics Semiconductors stepped in to supply the same reliable thermal fuses from original manufacturers—now under VET part numbers. You get genuine components that meet or exceed all original specs, plus responsive support and certificates of conformity on request.

NOTICE 1: As you may or may not already know. NTE is officially out of business and we are unable to order parts from them ever again.

However, we were able to locate the company that NTE used to make these Thermal Cutoffs (All NTE did was relabel product and resell it). This means that you may order the NTE part, but we may ship different part numbers that are the original parts that match the NTE specifications. Certificates Of Conformity are available from us, upon request.

NOTICE 2: These no longer come with the un-insulated crimp butt connectors that NTE used to include with them. If you need them, we recommend either ordering SR-BUT-2N. If you have a special need for them, you can always email us for more information and we are always here to help.
