Betterfuse Thermal Protectors
Quick Overview
The Betterfuse Thermal Protectors are compact, thermally operated snap-action devices designed to offer maximum protection in a minimal footprint. At the core of these protectors is a bi-metal snap-action strip that serves as the operational heart. When this strip reaches its calibrated temperature-triggered by a rise in ambient temperature, increased current flow, or both-it snaps open, creating an open circuit. This effectively interrupts the current flow, providing thermal protection. Once the system cools down, the Betterfuse automatically resets itself, allowing power to be restored to the circuit.

Thermal Protectors
Betterfuse offers a diverse range of thermal protectors, each designed for specific shapes and applications. These include round and flat designs, pressure-resistant or sealed options, and both current-independent and current-sensitive models. Despite these differences, all Betterfuse thermal protectors share a commitment to the highest quality and performance in temperature protection.
In addition to exceptional quality, Betterfuse provides competitive pricing and excellent customer service. Their products are widely used across various industries, including automotive, food service, compressors, A/C motors, transformers, and medical equipment. The increasing power density in electronic circuits and the trend towards miniaturization often result in dangerously high temperatures. Compact modules that house multiple functions typically exhibit high power consumption. Even minor increases in current in power electronics, with minimal power dissipation, can lead to temperatures soaring to approximately 200 �C. This can have serious consequences, including damage or detachment of nearby components, harm to the printed circuit board structure, and in the worst case, the risk of triggering a fire.
No Overheating With Thermal Protectors
Thermal protectors are essential for motor safety. When a motor overheats, the thermal protector disconnects the electricity, preventing potential fires. These protectors are installed internally within the motor and utilize a bimetal disc made of two different metals to break the electrical contact when the temperature threshold is exceeded. This feature can be customized based on the required temperature, size, and metal composition.
Choose From a Variety of Thermal Protectors
Betterfuse manufactures thermal protectors using a range of durable and precise materials, including brass, SS 316, CS, Hastelloy, and Titanium Monel. By starting with these high-quality materials, Betterfuse ensures their products are reliable and effective.
Overall, Betterfuse's thermal protectors provide robust and reliable temperature protection, making them an excellent choice for various industrial applications.
