SF214E Thermal Fuse Blade Fuse 10A 250V 216°C Cutoff – Vigor Source

Description

Product Overview

The SF214E thermal fuse is engineered to provide precise, reliable overload protection for a broad spectrum of electrical devices. Manufactured by Vigor Source, a trusted name in electrical components, this fuse combines a robust ceramic pipe with a high‑temperature sealing resin to deliver one‑shot operation at a rated current of 10 amps and a voltage rating of 250 V. The fuse is designed to interrupt the circuit when temperatures reach 216 °C, effectively preventing damage to connected equipment and reducing fire hazards. Its compact dimensions—3.6 × 2 × 0.2 inches—and lightweight construction (0.71 oz) make it easy to install in tight spaces, while the lead configuration allows for straightforward soldering or insertion into blade fuse holders. The SF214E meets stringent safety standards, offering cadmium‑free and lead‑free construction, which aligns with modern environmental regulations and ensures long‑term reliability. With a proven track record since its launch in December 2017, this fuse has earned a solid reputation among electricians and DIY enthusiasts alike.

Usage

Designed for versatility, the SF214E thermal fuse excels in a variety of household and commercial applications. It is an ideal safeguard for high‑current appliances such as irons, hair dryers, electric heaters, and refrigerators, where sudden temperature spikes can cause costly failures. In addition, the fuse performs reliably in industrial settings, protecting air conditioners, ventilation fans, gas boilers, and transformers from overload conditions. Its fast‑acting thermal cut‑out mechanism ensures that devices like coffee makers, rice cookers, and water pots shut down before reaching unsafe temperatures, extending product lifespan and enhancing user safety. The fuse also supports use in power adapters, chargers, battery packs, copiers, laser printers, and power taps, making it a universal solution for both consumer electronics and professional equipment. Installation is straightforward: simply replace the existing blade fuse with the SF214E, ensuring correct polarity and secure contact. Once installed, the fuse operates silently, monitoring temperature continuously and tripping only when necessary, thereby providing peace of mind for homeowners, technicians, and facility managers.

FAQ

What types of devices can I use the SF214E thermal fuse with?

The SF214E is suitable for any appliance that operates up to 10 amps and 250 volts, including irons, hair dryers, heaters, refrigerators, air conditioners, fans, transformers, chargers, and many other household or industrial devices.

How does the one‑shot operation work?

When the internal temperature reaches the preset limit of 216 °C, the fuse’s sealing resin melts, permanently opening the circuit. This single‑use action ensures the fault is isolated, preventing further damage.

Is the SF214E fuse replaceable after it trips?

Because the fuse operates on a one‑shot principle, it must be replaced with a new unit after tripping. Replacement is simple: remove the old fuse and insert a new SF214E of the same rating.

Does the fuse meet any safety certifications?

Yes, the SF214E complies with major safety standards for thermal fuses, including IEC and UL requirements, and is manufactured without cadmium or lead to meet environmental regulations.

What warranty does Vigor Source provide for this fuse?

Vigor Source offers a one‑year limited warranty covering manufacturing defects, backed by responsive technical support to assist with installation and any performance questions.
