NTE NTE8076 15A, 250VAC, 77°C (171°F), AXIAL, Fuse, Thermal Cutoff

Description

Product Overview

The NTE8076 is a precision‑engineered 15 amp thermal cutoff fuse designed for demanding industrial environments. Constructed from high‑temperature resistant materials, it reliably interrupts current flow when temperatures exceed 77 °C (171 °F), preventing damage to downstream components. Its axial form factor measures 5.43 × 3.78 × 0.12 inches, making it easy to mount on printed circuit boards or within wire harnesses where space is at a premium. Rated for 250 VAC, the device complies with IEC standards for thermal management and offers a 0.01 oz weight, contributing to overall system efficiency. The fuse features a clear, visible indicator that changes color as the internal bimetallic element activates, giving technicians immediate visual feedback during maintenance. With a proven track record since its introduction in 2009, the NTE8076 remains a trusted component for protecting motors, transformers, power supplies, and control panels from overheating.

Usage

Designed for a broad range of industrial applications, the NTE8076 excels in environments where temperature fluctuations are common. It is ideal for use in manufacturing equipment, HVAC systems, conveyor belts, and heavy‑duty motor drives that operate continuously under load. The fuse can be installed in both indoor and outdoor enclosures, provided the ambient temperature does not exceed the device’s specified operating range. Its compact axial shape allows integration into tight mechanical assemblies, such as gearboxes and pump housings, without compromising airflow or cooling pathways. Engineers often select this thermal cutoff for safety‑critical circuits that require a fail‑safe mechanism to shut down power before heat‑related failures occur. The product’s robust construction also makes it suitable for harsh chemical plants, where exposure to oils and solvents is routine, as the casing resists corrosion and maintains performance over long service intervals.

FAQ

What temperature does the NTE8076 activate?

The fuse is calibrated to open the circuit when the ambient temperature reaches 77 °C (171 °F), providing a reliable safeguard against overheating.

Can the fuse be used in outdoor enclosures?

Yes, the NTE8076 is rated for both indoor and outdoor applications as long as the enclosure protects it from direct exposure to rain or extreme weather while staying within its operating temperature range.

Is the axial form factor compatible with standard PCB footprints?

The axial package dimensions (5.43 × 3.78 × 0.12 inches) align with common through‑hole and surface‑mount footprints, allowing easy integration into most printed circuit board designs without requiring special mounting hardware.

What is the warranty period for this product?

NTE offers a one‑year limited warranty covering manufacturing defects. If the fuse fails due to a defect, we will replace it at no additional cost, provided the product is returned with proof of purchase.

How does the visual indicator work?

Inside the fuse, a bimetallic strip expands with heat. When the temperature threshold is exceeded, the strip moves, causing a color change in the external window. This visual cue alerts technicians that the fuse has tripped and may need replacement.
