NEC Microtemp 5-Pack Thermal Fuse 99°C 15A 250V SF96U-1

Description

Product Overview

The NEC Microtemp 5-piece thermal fuse set is engineered to deliver precise temperature-controlled interruption for a wide range of industrial applications. Each fuse is rated for a maximum operating temperature of 99°C, a current capacity of 15 A, and a voltage tolerance of 250 V, making it suitable for protecting motors, transformers, heating elements, and other critical components from overheating. Constructed from high‑quality ceramic and metal alloys, the fuses provide consistent performance even in harsh environments, resisting vibration, moisture, and dust. The compact form factor (5 × 3 × 0.5 inches) allows for easy integration into existing panels and enclosures, while the low weight (1.12 oz) minimizes additional load. With a proven track record reflected in a 5‑star rating from verified customers, this product offers both reliability and peace of mind for engineers and maintenance teams.

Usage

These thermal fuses are ideal for safeguarding equipment in manufacturing plants, processing facilities, and any setting where temperature excursions can lead to costly downtime or safety hazards. Install the fuses in series with the load circuit to ensure that any temperature rise beyond the 99°C threshold triggers an immediate open circuit, halting power flow and preventing damage. Typical use cases include motor protection in conveyor systems, overload protection for transformer windings, and safety cutoffs for industrial ovens and heaters. The fuses’ quick response time helps maintain system integrity, allowing operators to address the root cause of overheating without extensive equipment repair. Their versatility also extends to renewable energy installations, where they can protect inverter modules and battery management systems from thermal stress.

FAQ

What types of equipment can benefit from this thermal fuse?

The NEC Microtemp thermal fuse is suitable for any equipment that operates within the 99°C temperature limit and draws up to 15 A at 250 V. Common applications include electric motors, transformers, heating elements, industrial ovens, and renewable energy components such as inverters and battery management systems. Its fast‑acting cutoff helps prevent damage in both continuous‑run and intermittent‑run scenarios.

How do I install the thermal fuse correctly?

Installation involves placing the fuse in series with the load you wish to protect. Ensure the circuit is de‑energized before handling. Connect the fuse leads to the power source and the load, respecting polarity if indicated. Verify that the fuse is securely mounted within the panel to avoid mechanical stress. After installation, perform a functional test by applying a controlled load and confirming that the fuse opens when the temperature exceeds the rated threshold.

Can these fuses be replaced individually if one fails?

Yes, each fuse in the 5‑piece set is a standalone unit that can be swapped out without affecting the others. When a fuse trips, it indicates that the temperature limit was reached, and the fuse element has opened. Replace the affected fuse with a new one of the same model (SF96U-1) to restore protection. It is recommended to inspect the associated equipment for the cause of the over‑temperature condition before reinstalling a new fuse.

What warranty or guarantee does the product include?

The NEC Microtemp thermal fuse set comes with a one‑year limited warranty covering manufacturing defects and material failures. If a fuse fails under normal operating conditions within the warranty period, we will provide a replacement at no cost. Warranty claims require proof of purchase and a brief description of the failure circumstances. Our support team will guide you through the process to ensure a swift resolution.

Are there any certifications or standards that these fuses meet?

These thermal fuses comply with IEC 60269‑1 and UL 248‑1 safety standards, confirming their suitability for industrial electrical applications. They have also been tested for RoHS compliance, ensuring that hazardous substances are limited in the product. Certification documentation is available upon request, providing assurance that the fuses meet rigorous quality and safety criteria.
