PTC resettable fuses are different from other types of fuses because they have the ability to sense an overload condition in the circuit, automatically open the circuit, and then reset themselves when the overload condition is eliminated. This type of fuse is sometimes referred to as a poly-fuse or polymeric positive temperature coefficient fuse.

The PTGLCSAS2R2K4B51A0 is one type of PTC resettable fuse. This is a device designed to protect circuits against overcurrent and short circuit fault protection. It is a surface mount, current-limiting heavy duty fuse rated at 16 Volt with a current rating of 20 Amps.

Application Field

The PTGLCSAS2R2K4B51A0 is typically used in automotive, industrial, and medical electronic applications, such as PC boards, electronic control systems, motors, and batteries. Automotive applications often include electric and hybrid vehicles, while industrial uses can range from computers to lighting systems.

Due to its robust construction, the PTGLCSAS2R2K4B51A0 is ideal for automotive applications, such as electric and hybrid vehicles, which require exceptional reliability. It is also well suited for other transportation applications, such as rail vehicles, buses, and aircraft. The fuse is also suitable for critical circuitry in industrial and medical applications, providing the highest levels of protection.

Working Principle

The PTGLCSAS2R2K4B51A0 operates on a thermally-sensitive, self-resetting principle. As the current passing through the fuse increases, the temperature rises. Once the temperature exceeds the fuses thermal trip level, the trip function is initiated, and the fuse opens and remains open until the temperature falls below the thermal trip level and the thermal reset function is activated. This self-resetting capability eliminates the need for manual resetting, resulting in improved safety and performance in commercial and automotive applications.

When the temperature rises to the thermal reset level, the fuse automatically resets itself, allowing normal conditions to resume. This means that the PTGLCSAS2R2K4B51A0 is a highly reliable solution for circuits that are subject to repeated overloads or are subject to dynamic current conditions.

The unique design of the PTGLCSAS2R2K4B51A0 also allows for improved thermal performance in electronic circuits. Its low internal resistance, coupled with a precisely controlled thermal trip level, can reduce inrush currents, improve component life, increase system reliability, and reduce costs.

The PTGLCSAS2R2K4B51A0 is an essential component for protecting circuits against overcurrent and short circuit fault protection. Its ability to self-reset, its reliable and robust design, and its high thermal performance make it an ideal solution for a wide range of applications.
