Garosa 4Pcs Ceramic Thermal Protector – 250V 15A 125C Cutoff Switch

Description

Product Overview

The Garosa 4‑piece ceramic thermal protector kit is engineered to provide precise over‑temperature protection for a wide range of industrial and consumer electrical applications. Each unit features a compact 0.39 × 0.39 × 0.39 inch ceramic body housed in a robust ABS shell, ensuring resistance to mechanical shock and chemical exposure. The internal alloy wire delivers a low‑resistance path that reliably triggers at the calibrated 125 °C cutoff point, instantly opening the circuit when the temperature exceeds the safe threshold.

Designed for a maximum voltage of 250 V and a current rating of 15 A, the protector is suitable for both single‑phase and three‑phase systems commonly found in air‑conditioner motors, transformers, and other thermal appliances. The product dimensions and lightweight construction (0.74 oz) make it easy to install in tight spaces, while the ceramic element provides excellent thermal conductivity for rapid response. With a best‑seller rank of #27 in the Thermal Cutoffs category, this kit has earned a reputation for reliability among engineers and hobbyists alike.

Usage

Garosa thermal protectors are ideal for safeguarding motor windings in household appliances such as air‑conditioners, refrigerators, and washing machines. They also excel in protecting power supplies and transformer windings in industrial equipment where overheating can lead to costly downtime. Install the protector in series with the load circuit; when the ambient or internal temperature reaches 125 °C, the ceramic element expands, breaking the circuit and preventing further heat buildup.

Because the kit includes four interchangeable units, users can replace a failed protector without ordering a new part, reducing maintenance time and inventory costs. The protectors are compatible with standard PCB mounting holes, allowing for straightforward solder‑free installation in both new designs and retrofits. Whether you are an OEM engineer designing a new product line or a field technician performing on‑site repairs, the Garosa thermal cutoff provides a dependable safety mechanism.

FAQ

What does the 125 °C cutoff rating mean?

The 125 °C rating indicates the temperature at which the ceramic element expands enough to open the circuit, stopping current flow to prevent overheating of the connected device.

Can I use these protectors in a three‑phase system?

Yes, the protectors are rated for up to 250 V and 15 A, making them suitable for both single‑phase and three‑phase installations commonly found in industrial equipment.

How do I replace a failed protector?

Simply disconnect power, remove the faulty unit from its mounting hole, and insert a new protector from the kit. No soldering is required, and the design ensures a secure fit.

Is there a warranty on these protectors?

Garosa provides a one‑year limited warranty covering manufacturing defects, and our support team is available to assist with any warranty claims or technical inquiries.

Are these protectors compatible with PCB mounting?

Yes, each protector includes standard mounting holes that align with common PCB layouts, allowing for easy integration into existing circuit boards.
